Electrically controlled frequency reconfigurable comb type antenna is presented in this paper. Reconfigurability is achieved by placing a PIN diode in each slot of the comb type antenna. The proposed antenna has very compact size and works on 8 different bands depending upon the state and number of PIN diode (ON/OFF). Ansoft Designer 7 is used to simulate the equivalent model for the PIN diode and proposed antenna is fabricated on FR4 substrate using photolithography process. As the antenna reconfigure its resonating frequency from 1st band to 8th band, directivity increases from 3.28 to 4.02 and radiation efficiency increases from 75.3% to 93.45% due to the improvement in impedance matching at higher band.

Abstract In this paper, a novel design for miniaturization of microstrip patch antenna with multiband operation of microstrip antenna is proposed. The technique is based on etching out of Complimentary Split-Ring Resonator (CSRR) on the radiating edge of the patch antenna. Numerical simulations are presented for a patch antenna with and without CSRRs by using IE3D simulation software and measured practically. The measured results shows that antenna with CSRRs on the radiating edge of the patch antenna is resonating at four different frequency points i.e., 4.96GHz, 6.05GHz, 8.62GHz and 11.25GHz., whereas, antenna without CSRR i.e., conventional microstrip antenna is resonating at 5.98GHz. The size reduction of 16.92% is achieved and the antenna gives the overall bandwidth of 17.88%. These antennas find application in Wireless Communications. Keywords: microstrip antenna, CSRR, return loss, miniaturization, bandwidth.

Gain is the ability of an antenna to concentrate the radiated power in a desired direction. Only small gain can be achieved by single antenna that is why, antenna arrays are required to improve the gain by using different feed networks. This paper describes the design and performance of a series feed antenna array. The operating frequency of 2.4GHz is used. The aim of this paper is to improve the gain of a series feed antenna array. Line feed is used for designing single antenna, 2x1 & 4x1 microstrip antenna array. These series feed microstrip antenna arrays are useful for both S and C band. The proposed antenna is simulated by IE3D version 9.0 Zealand simulation software based on method of moments.

This work presents a Neural Network model for the design of Microstrip Antenna for a desired frequency between 3.5 GHz to 5.5 GHz. The results obtained from the proposed method are compared with the results of IE3D and are found to be in good agreement. The advantage of the proposed method lies with the fact that the various parameters required for the design of specific Microstrip antenna at a particular frequency of interest can be easily extracted without going into the rigorous time consuming, iterative design procedures using a costly software package. In this work, a general design procedure is suggested for the Microstrip antennas using artificial neural networks and this is demonstrated using the rectangular patch geometry.

In this paper we propose a rectangular microstrip patch antenna with inset fed which can operate at 2.4 GHz (IEEE 802.11b) & 5.8 GHz (IEEE 802.11a) WLAN applications. Various slot is cut into the antenna structure which changes the surface current path resulting in dual resonant frequency. Further by embedding any switch into a slot, reconfiguration can be achieved i.e. the antenna can only be used in unlicensed 2.4 GHz band. The achieved directivity is greater than 5db and the bandwidth obtained is much greater than the required bandwidth. The proposed antenna is simulated using High Frequency Structure Simulator.

Cube satellite missions perform innovative scientific experiments on a low cost developmental platform but have an inherent limitation of size and space. This restricts the total available solar power that can be harnessed and as a result, the radio links operate on stringent power budgets. For improving the available margins for communication in such satellites, it is desirable to improve upon the antenna system performance at the ground station used for the establishment of the links with the satellite. This can be achieved by improving the forward gain, the forward to backward ratio and the directivity of the antenna. This paper describes the electrical simulations and the performance evaluation of the one unit, two unit and four unit circularly polarized crossed Yagi-Uda antenna array designed for communication with amateur radio (HAM) satellites operating over the 434 MHz to 438 MHz Amateur UHF band. The electro-magnetic model has been developed using the 4NEC2 software. The simulations have been validated with the practical field testing performed for estimating the SWR, antenna gain, the forward to backward ratio and radiation pattern for the antenna system.

The aim of this work is to miniaturize microstrip patch antenna array resonating at 3.8 GHz suitable for WiMax application using defected ground structure (DGS).The DGS has been employed to shift the resonance frequency of an initial microstrip antenna array from 5.2 GHz to 3.8 GHz by disturbing the antenna’s current distribution. The proposed DGS is integrated in the ground plane under the patch antenna array for size reduction. Finally, the miniaturization up to 45% with respect to the conventional microstrip antenna is successfully accomplished. A prototype of the antenna was fabricated with the RT-Duriod substrate. This technique has been validated experimentally and measured results were found to be in good agreement with simulated results.

In this work, a compact dual-band semi-flexible antenna operating at 2.45 GHz and 5.8 GHz for the industrial, scientific and medical (ISM) band is presented. The antenna is fabricated on a semi-flexible substrate material, Rogers Duroid RO3003™ with a low-profile feature with dimensions of 30×38 mm2 which makes it a good solution for wearable applications. Bending investigation is also performed over a vacuum cylinder and the diameters are varied at 50 mm, 80 mm and 100 mm, that represents the average human arm’s diameter. The bending investigation shows that reflection coefficients for all diameters are almost similar which imply that the antenna will operate at the dual-band resonant frequencies, even in bending condition. The simulated specific absorption rate (SAR) in CST MWS® software shows that the antenna obeys the FCC and ICNIRP guidelines for 1 mW of input power. The SAR limits at 2.45 GHz for 1 g of human tissue is simulated at 0.271 W/kg (FCC standard: 1.6 W/kg) while for 10 g is at 0.0551 W/kg (ICNIRP standard: 2 W/kg. On the other hand, the SAR limits at 5.8 GHz are computed at 0.202 W/kg for 1 g and 0.0532 W/kg for 10 g.

ABSTRACT: This paper examines the applicability of the Okumura - Hata model in Malaysia in GSM frequency band. The study was carried out in the open area only since measurements provided from Malaysia Mobile were about the open areas. The mean square error (MSE) was calculated between measured path loss values and those predicted on basis of Okumura-Hata model for an open area. The MSE is up to 6dB, which is an acceptable value for the signal prediction. Therefore, the model gave a significant difference in an open area that allowed necessary changes to be introduced in the model. That error was minimized by subtracting the calculated MSE (15.31dB) from the original equation of open area for Okumura-Hata model. Modified equation was also verified for another cell in an open area in Malaysia and gave acceptable results.

This study deals with a new research work on a low cost multiband printed antenna which can be used for three operating frequency bands GSM900/PCS/WIFI/Bluetooth. The achieved antenna is mounted on an FR-4 substrate. In this study, the solts technique is used to obtain the multiband behavior. The different solts are inserted in the radiator face and the back face that is the ground. The whole circuit is optimized taking into account the good matching of the input impedance in the operating frequency bands with a stable radiation pattern. In order to optimize the proposed antenna structure we have used CST-MW and to compare the obtained simulation results we have conducted another electromagnetic simulation by using HFSS solver. The final circuit validated into simulation has been fabricated and tested which permits to validate the proposed multiband antenna.

Proper narrowband antenna design for wearable devices in the biomedical application is a significant field of research interest. In this work, defected ground structure-based microstrip patch antenna has been proposed that can work for narrowband applications. The proposed antenna works exactly for a single channel of ISM band. The resonant frequency of the antenna is 2.45 GHz with a return loss of around -30 dB. The -10dB impedance bandwidth of the antenna is 20 MHz (2.442-2.462 GHz), which is the bandwidth of channel 9 in ISM band. The antenna has achieved a high gain of 7.04 dBi with an increase of 17.63% antenna efficiency in terms of realized gain by using defected ground structure. Three linear vector arrays of arrangement 1 2, 1 4 and 1 8 have been designed to validate the proposed antenna performances as an array. The proposed antenna is light weighted, low cost, easy to fabricate and with better performances that makes it suitable for biomedical WLAN applications.

The key areas usually covered include: Fundamentals of Genetics: - Mendelian inheritance - Chromosome structure and function - Genetic variation and mutation Plant Breeding Techniques - Hybridization methods - Selection techniques - Breeding for disease resistance Molecular Genetics - DNA replication, transcription, and translation - Molecular markers in plant breeding - Genomics and genetic engineering 4. Quantitative Genetics: - Heritability and genetic advance - Statistical methods in plant breeding - QTL mapping #### Detailed Question Paper Analysis Now, let's analyze a previous year’s question paper to understand the types of questions asked and the best ways to approach them. Section 1: Fundamentals of Genetics Example Question: Which of the following is NOT a part of Mendel's Laws? - A) Law of Segregation - B) Law of Independent Assortment - C) Law of Dominance - D) Law of Uniformity Analysis: This question tests your basic understanding of Mendelian genetics. To tackle such questions, ensure you are well-versed with the core principles of genetics. Revising basic concepts from standard textbooks like "Principles of Genetics" by Gardner et al. can be highly beneficial. Section 2: Plant Breeding Techniques Example Question: In plant breeding, the method where two plants with desirable traits are crossed is known as: - A) Backcrossing - B) Hybridization - C) Mutation breeding - D) Polyploidy Analysis: Questions in this section often require applied knowledge of breeding techniques. Focus on understanding the different methods of plant breeding, their applications, and examples. Books like "Plant Breeding: Principles and Methods" by B.D. Singh can provide comprehensive coverage of these topics.
