Patel4 Abstract—In this paper Microstrip radiating structure with Complementary Split Ring Resonator (CSRR) using Curve Tooth with two different substrate material for Multiband applications in S band and C band is designed and analyzed. We have introduced Curve Tooth in CSRR to improve Gain in comparison with simple CSRR based design. Also, The same design with two different substrate material like FR4 and Teflon is compared and analyzed. Here, Patch of dimension 44Ãâ€"44mm2 is analyzed. The FR4 based design of Curve Tooth in CSRR has five working bands centered around 1580 MHz, 3180 MHz, 3600 MHz, 4580 MHz, 7190 MHz and Simple CSRR Design has three working bands with center frequency 1560 MHz, 3150 MHz and 3540MHz. The Teflon based design of Curve Tooth in CSRR has five working bands centered around 2250 MHz, 4560 MHz, 5150 MHz, 6540 MHz, 8310 MHz and Simple CSRR Design has four working bands with center frequency 2213 MHz, 4508 MHz, 5050MHz and 6395 MHz. Design results of VSWR, R eturn loss S11 and Total Gain of all four design is shown and compared in this paper. Also, Design results shows improvement in Gain in Curve Tooth CSRR design. The dimensions of substrate height is 1.57 mm, Patch and Ground height is 0.035 mm which are similar to actual Antenna dimensions. Design results are obtained by a HFSS 13 (High Frequency Structure Simulator) which is mostly used for simulating microwave passive components.

Introduction Nowadays, Multiband antenna is a popular choice because same antenna can be used for many applications [12][15][17][18][19]. Microstrip patch antennas are widely used because of their many merits, such as the low volume, light weight, low cost etc. [1-8] However, Patch antennas have a main disadvantage: narrow bandwidth while others are low gain, low power handling capacity etc. [1-8] Still there is a need to design Multiband antenna with improvement in Gain. Metamaterial may solve this need. In Recent Scenario, Microstrip patch antennas are widely used in wireless devices and other compact sizes with multiband antenna operation. The irregular shape of the developed planar antenna achieves multi-band (Broadband) performance [11]. In traditional planar antennas, the distances between the edges are fixed and therefore, the antennas dominant mode resonates only at a single frequency [11]. In contrast, the irregular shape of the current antenna facilitates, its broadband character by allowing the structure to have more than one degenerate mode that resonate at more than one frequency, based on the irregularity introduced [11]. In general, multi-sided patches are excellent candidates for broadband operation, since many closely spaced resonant modes can be excited using the different edges of the patches [11]. This property makes them uniquely suited for multi-band operation in wireless applications. There has been a considerable amount of recent interest in the class of artificial material which is known as Metamaterials that possess simultaneously negative permeability and permittivity, according to a negative index of refraction [1][2]. Such type of metamaterial is known as a double negative material (DNG). To increase the power radiated from electrically small antennas, an application of DNGs has been suggested by Ziolkowski and Kipple [3]. But in this paper a negative permittivity material complementary split ring resonator (CSRR) which is a dual counterpart of split ring resonator (SRR) originally proposed by Pendry have been loaded into the patch. CSRR is composed of two concentric metallic ring slots with slits etched in each ring at its opposite sides. Apart from double negative materials, single negative materials where only one of the material parameters has a negative real value also possess interesting properties and can be used to produce novel devices. In particula r the complementary split ring resonator (CSRR) which establishes a negative-permittivity at resonance, is an example of a single negative media (SNG) that can be used to make microwave devices [4]-[6]. Here, we have incorporated curve tooth CSRR to further improve the results of CSRR. The properties of SNG can also be manipulated to increase filter shape factor, improve filter rejection and can also applied to antennas to reduce the spurious effect and increase antenna gain and antenna size reduction [7][9][16][17]. This paper is based on the microstrip radiating structure which integrates a Curve Tooth CSRR design into the ground to provide good return loss and improved gain. The CSRR is a commonly used resonator etched on the Metal plane. An effective negative permittivity and negative permeability could be introduced in microstrip devices by loading CSRR [17][18]. In this article, we have etched the CSRR in the ground plane of a microstrip patch underneath the substrate. The CSRR structure model is shown in Figure 1. If the effects of the metal thickness and losses, as well as those of the dielectric substrate are ignored, a perfectly dual behavior is expected for the complementary screen of the SRR. Thus, whereas the SRR can be mainly considered as a resonant magnetic dipole that can be excited by an axial magnetic field, the CSRR (Fig. 1) in essence behaves as an electric dipole (with the same frequency of resonance) that can be excited by an axial electric field. Fig. 1 shows the unit cell structure of SRR model and CSRR model with its equivalent electrical circuit. Fig. 1 (a) SRR unit cell, (b) Equivalent electric circuit of SRR unit cell, (c) CSRR unit cell, and (d) equivalent electric circuit of CSRR unit cell. [15] II. Design and Simulation In this section, we will introduce the design of our antenna. First the conventional patch length and width is designed. After designing the patch, we have taken out five slots from the patch to improve the radiation path. Basic length and width is designed with the use of following equations [5]. Width of the patch can be designed using the equation (1), here f0 is the resonance frequency, ÃŽ µr is relative permittivity of the dielectric substrate and c is speed of light. Length of the patch can be designed by using the equations (2-5) [5]. Here‘t’ is the thickness of substrate. Using these equations we have derived length and width of conventional patch. We designed square patch so length and width are same and it is 44 mm, so a square patch is 44Ãâ€"44 mm2 over here which is shown in Figure 2 (a). We have taken out five slots from the patch to increase the Radiation path and to improve the results as shown in figure. The slots taken out have dimension of 8Ãâ€"8 mm2. A. Design 1 The top view of the Simple CSRR design and Curve tooth with CSRR Design is shown in Figure 2 (a) and 2 (b) respectively. Both the design has outer and inner ring is of 1 mm. Gap between the two rings is 1.5 mm. Table: 1 Material used for Design1 Design 1 Material Patch Copper Substrate Teflon with ÃŽ µ = 2.1 Table 1 shows details about the material. Patch is of copper material. Substrate is of Teflon material with ÃŽ µ = 2.1. The base material is also of copper. Fig. 2 (a) HFSS Model of Simple CSRR Design Fig.2 (b) HFSS Model of Curve Tooth CSRR Design For simulation we used HFSS 13 (High Frequency Structure Simulator) of Ansoft, which is very good simulator for simulating microwave passive components specially RF antenna. Figure 3 (a) and 3 (b) shows the Return Loss (S11) in dB for both the designs. The minimum return loss which we are getting for Simple CSRR design is -31 dB for the band centered around 4.508 GHz and for Curve Tooth CSRR design, it is -37 dB for the band centered around 4.56 GHz. Figure 4 (a) and 4 (b) shows the VSWR plot for both the designs.

Figure 6(a) and 6(b) shows VSWR plot for both the design. III. Comparative Analysis A. Design 1 In this design, we used Teflon as a substrate material in which Curve Tooth design has five working bands while Simple CSRR design has four working bands. Table 3 shows comparison of Return loss and VSWR of the both the design. Table 3 : Comparison of S11 and VSWR for both design Band Design Frequency in GHz Minimum Return Loss (S11) in dB VSWR First CSRR 2.213 -18.8 1.2601 Curve tooth CSRR 2.25 -17 1.331 Second CSRR 4.508 -31 1.0549 Curve tooth CSRR 4.56 -37.6 1.0268 Third CSRR 5.05 -15 1.4183 Curve tooth CSRR 5.15 -14.8 1.4434 Fourth CSRR 6.395 -27.7 1.0862 Curve tooth CSRR 6.54 -24.7 1.1243 Fifth CSRR Curve tooth CSRR 8.31 -12 1.6624 By using curve tooth in CSRR, we have an extra working band and also return loss and VSWR values are very good. We got VSWR of 1.0268 using curve tooth which is nearer to 1. Figure 7(a) and 7(b) shows Total Gain plot in 3D view for CSRR and Curve tooth CSRR design respectively. Fig.7 (a) Total Gain plot in 3D view for simple CSRR design Fig.7 (b) Total Gain plot in 3D view for Curve Tooth CSRR design Simple CSRR design has Total Gain of 2.6609 dB while Curve Tooth CSRR design has Total Gain of 2.9264dB. So using Curve tooth in CSRR we have improved gain. B. Design 2 In this design, we used FR4 epoxy as a substrate material in which Curve Tooth design has five working bands while Simple CSRR design has four working bands. Table 3 shows comparison of Return loss and VSWR of the both the design. By using curve tooth in CSRR, we have two extra working bands and also return loss and VSWR values are very good. We got VSWR of 1.0931 using curve tooth which is nearer to 1. Figure 8(a) and 8(b) shows Total Gain plot in 3D view for CSRR and Curve tooth CSRR design respectively. Simple CSRR design has Total Gain of -0.2895 dB while Curve Tooth CSRR design has Total Gain of 3.0368dB. So using Curve tooth in CSRR we have sufficiently increased the gain.

Conclusion Here Microstrip patch antenna is designed for multiband applications using five rectangular square slots in the Patch and CSRR in ground. Curve Tooth is also implemented in CSRR to improve the results. Two designs with different substrate material is designed and analyzed. This antenna is compared with simple CSRR design. The result of Design 1 which has Teflon substrate, indicates the five working bands for Curve Tooth CSRR design, 2.25 GHz, 4.56 GHz, 5.15 GHz, 6.54 GHz and 8.31 GHz so the antenna can used for S and C Band Applications while Simple CSRR has four working bands. VSWR is very good for 4.56 GHz frequency which is 1.0268 near to 1. Also, Gain has been improved with Curve Tooth CSRR which is 2.9264 dB compare to Simple CSRR design which has gain of 2.6609 dB. Design 2 which has FR4 substrate, provides five working bands for Curve Tooth CSRR while CSRR design has three working bands. Also, Gain for Curve Tooth CSRR has 3.0368 dB compare to -0.2895 dB for simple CSRR design . So, by using Curve Tooth in CSRR improves results. Also, Dimensions of all Designs are similar to Actual Antenna so when we fabricate the antenna, we will get similar results. References V.G.

Longitudes and Attitudes, by Thomas Friedman :: September 11th Essays

  Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Longitudes and Attitudes†, written by Thomas Friedman, is a collection of columns, broken by September 11th’s great catastrophe and including material from his diary. The book displays his outstanding strengths as a commentator along with a few weaknesses.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Longitudes and Attitudes† is a collection of his more recent columns and a diary of supporting incidents. It relates to the theme that has consumed him in his career. This theme is given point by Israeli-Palestinian conflict and the attack of 9/11.   Ã‚  Ã‚  Ã‚  Ã‚  Born in Minneapolis, Minnesota, Tom Friedman went to work as a journalist in Beirut, Lebanon soon after securing a masters degree from Oxford University in Middle Eastern Studies. Employed by United Press International in 1978, he soon transferred to the New York Times and covered the Syrian destruction of that country’s own town of Hama, the Israeli Lebanese invasion, the massacre of Palestinians in refugee camps, the evacuation of the Palestinian Liberation Organization, etc. In 1995, he became the foreign affairs columnist for the New York Times with carte blanche--unlimited travel budget and no supervision as to content. He has written two books and collected three Pulitzer Prizes.   Ã‚  Ã‚  Ã‚  Ã‚  In his current job, Friedman writes a 740-word column twice a week. It appears in many of the world’s newspapers and on the Web. This latest book, Longitudes and Attitudes, is a compendium of his more recent columns and a diary of supporting incidents. The text relates to the theme that has consumed him in his career: the failure of the Arab nation to develop, democratize, and compete properly with the West. This theme is given point by the Israeli-Palestinian conflict and the attack of 9/11.   Ã‚  Ã‚  Ã‚  Ã‚  Friedman’s ideas are presented primarily through many columns that he had written for he New York Times. Their datelines stretch from December 15, 2000 to April 20, 2003 and from Jerusalem, Israel to Peshawar, Pakistan.   Ã‚  Ã‚  Ã‚  Ã‚  In this book, Friedman presents a coherent picture of forces in the Middle East that have led to the Israeli- Palestinian confrontation and to bin Laden and his group of terrorists. Friedman’s articles describe meetings, discussions, and arguments he had with people at all levels of society through out the Middle East. From his extensive travels and through dynamic interactions with the people he derived intense insights into how 9/11 came about, why, and what should be done about it.   Ã‚  Ã‚  Ã‚  Ã‚  His arguments and conclusions are well thought through, so much that they draw opponents to reason with him.

Comparing the Republic to the Modern Society Essay

The relevance of The Republic to our modern society In Plato’s The Republic, Plato illustrates what his ideal city would look like. He describes the educational systems, ideal legislators and the purposes of democracy. The republic influenced many people to understand the purpose for democracy, and it led to new philosophical schools of thought. Although this work was written hundreds of years ago, it still affects our modern world today. One of the most important things that Plato stresses is the importance of education. Without education of the masses, democracy would cease to exist. When Plato was forming his ideal society, he stressed the importance of education for several reasons. Most importantly, educating citizens led to a peaceful, well-run republic. For Plato, education was not about information intake and data storage. Rather, education was drawing out the knowledge that was already in the student. He said that â€Å"the power and capacity of learning exists in the soul already† He gives an allegory of prisoners in a cave, who have never seen light before. They become free, come out of the cave and see the light. They understand that the shadows are just reflections of real things; they are not the real things themselves. They ascend up to a mountain and see the world for what it really is. Plato uses this story to illustrate what education does for the human soul. We are all born in a dark cave, chained to a wall and cannot see the light. We still around all day looking at shadows, which appear to be so real to us. Education breaks the chains of ignorance. We can ascend to the top of the mountain and look out onto the beautiful world. According to Plato, after the prisoners’ ascend all the way to the top of the mountain, â€Å"they must be made to descend again among the prisoners’ in the den and partake in labors and honors, whether worth having or not. † Plato notes that once a person is educated and has received knowledge and truth, they should go back and teach those who do not know. This still relevant today because we need to not be so focused on how high we climb up the ladder, but we need to be concerned with how we help others achieve their goals. This allegory is also used to describe justice. The prisoners’ in the cave do not know what real justice looks like. The people on the mountain tops must come down and give understanding to those who are lacking it. Plato goes on to describe the type of leader that would be perfect to run the ideal city. The type of leader that Plato describes is someone who is â€Å"wisest about the affairs of the state, and by whom the state is best administered and who at the same time have other honors and a better life then that of politics. â€Å" The ideal leader in Plato’s time is not much different from the ideal leader in our time period. We still want someone who knows and understands the problems of the state or country, who will be a good leader, and will be able to put the welfare of his people before his own. These characteristics are still what many people look for in a dependable leader. Plato describes that a good leader should not be caught up in their own wealth, they should care about their people. This is a very foundational idea that is still important in America today. We desire to have a leader who will be humble and care for us, instead of one that has a hidden agenda. According to Plato, economic self-interest and political power must be kept separate and not be allowed to work in combination to the disadvantage of the state. In mapping out his utopian society, Plato stresses the importance of democracy. In a short piece called democracy considered, Plato talks about how oligarchies decay into democracies and democracies decay into tyranny. Tyranny is formed from pursing one’s pleasures and appetites. Plato claims that â€Å"a man who is deranged and not right in his mind will fancy that he is able to rule, not only over men, but also over gods â€Å"He describes here that a man can not be a leader if he is deranged and thinks that he is the center of the universe. Plato then shows how democracy and tyranny differ. In describing the differences, Glacon says â€Å"They are the opposite extremes for one is the very best and the other is the very worst. † The republic shows many similarities to today’s society. We still have many of the same ideals in education and in government. This piece of work was criticized at the time it was written by is now honored and very influential. It was one of the first writings that began western thinking and formed many new beliefs that influenced the renaissance.

MLK - I have a Dream essays

MLK - I have a Dream essays Martin Luther Kings I Have a Dream delivers a powerful message driven by dreams of brotherhood and equality. The speech not only appeals to the same dreams shared by his listeners but also to their sense of reason and understanding that their goal is to right and undeniable wrong. Through different analogies and historical references, Dr. King is able to create a stirring and emotional speech sure to bring out the best in all who listen to it. King goes to great lengths to draw valid comparisons between the Negros plight and, of all things, banking. By doing this, Dr. King is able to simplify what could be construed as a complex argument into the basic process of cash(ing) a check. However, in the Kings speech, the person giving out the check is America and, much to his and the Negro peoples discontent, the check is being returned for insufficient funds. King believes that once the check can be cashed, the Negro people will be able to demand the riches of freedom and security of justice. King continues to make more analogies when he begins to draw comparisons between freedom and nature. King believes that that black people should rise from the dark and desolate valley of segregation to the sunlit path of racial justice. This is an appeal to those not in the fight to rise up and begin demanding justice. No one should have to live their lives in a desolate valley but rather should escape the quicksands of racial injustice and climb the solid rock of brotherhood. King even goes on to describe the racial climate as a sweltering summer which will not pass to autumn until freedom and equality are there for all to share. This can be seen as a warning to the movements opposition that, yes, the Negro people are infuriated and will fight, though peacefully, until justice has rained down acros...

Ad Proposal for Apple 2014 - Essay Example EXECUTIVE SUMMARY The principle intention of the paper is to analyze the present marketing strategy of Apple Inc (Apple) and depict the strengths and weaknesses of the same, which would further be considered for strategizing future campaigns. Contextually, keeping in consideration the strengths and loopholes of advertising in Apple, a proposition has been made to the company, aiming at its launch of an ad campaign in the succeeding year, i.e. 2014. This proposal has been based on the analysis of the past records of the advertising strategies adapted by Apple, which were further assessed from a critical point of view in order to identify its strengths and weaknesses, with respect to the ad campaigns. Observably, the main strength of advertising approach of the company is its simplicity and its ability to ensure emotional connectedness with the targeted customers. However, the company is seen to be somewhat reluctant towards targeting the non-competitive market with the help of its adv ertising, which has remained to be a debatable topic in the recent years. Contextually, a proposal has been made planning the future advertising campaigns of Apple, which has focused on enhancing the appeal of the advertising on the competitive and the non-competitive markets along with insuring maximum innovation of the same keeping the company’s strengths and weaknesses into account. ...
