Study and Design of Microstrip Antenna
International Journal of Science and Research (IJSR)
This paper is about the theoretical and practical study of Microstrip antennas. In the paper we have simulated the results of two rectangular microstrip patch antenna and fabricated them into a single patch that works on multi frequency operations. For the same we have taken two antennas of frequency 9 GHz and 5.67 GHz and impedance matching is done at 50ohm. The feed is coaxial feed with corner excitation The antennas after being rearranged with corner excitation is investigated for operating frequency, return loss and radiation pattern. The rearranged structure shows reduction in resonant frequency. The pattern of radiation seems to be almost same. The frequency of the rearranged antenna is perceived to have increased from before. The whole simulation work is done on HFSS software.
IJERT-Analysis of Microstrip Antennas
International Journal of Engineering Research and Technology (IJERT), 2018
https://www.ijert.org/analysis-of-microstrip-antennas https://www.ijert.org/research/analysis-of-microstrip-antennas-IJERTCONV6IS13018.pdf Wireless technology is one of the main areas of research in the world of communication systems today and a study of communication systems is incomplete without an understanding of the operation and fabrication of antennas.This was the main reason for our selecting a project focusing on this field.The goal of this project is to analyse the Microstrip Patch Antenna which covers the GSM Band 0.8 to 1.9 GHz. This project covers study of basics and fundamentals of microstrip patch antenna. A series of parametric study were done to find that how the characteristics of the antenna depends on its various geometrical and other parameters. The various geometrical parameters of the antenna are the dimensions of the patch and ground planes and the separation between them and it also includes the dielectric constant of the substrate material.The parametric study also contains the study of different techniques for optimizing the different parameters of antenna to get the optimum results and performance. This is a simulation based study. The simulation of the antenna is carried out using Antenna magus simulation software and verified through matlab code. The simulation results of antennas indicate that the proposed antenna fulfils the excellent band characteristics for various frequency bands and showing the good return loss and radiation patters in the interested GSM band.
Study of Impedance-matching and Other Characteristics of Microstrip Antennas
Journal of Computer Science and Information Technology, 2015
In this paper I present the study and techniques used to find the modes of a microstrip patch antenna, match the antenna to the feed line and to measure the most important characteristics of the antenna (input response, far-field radiation patterns and polarization). The operating frequency of the antenna was found to be 1765MHz and a reflection coefficient of-65.46dB at 6.79mm from the edge of the rectangular antenna. The-10dB bandwidth of the antenna was found to be 83MHz and the wideband frequency response also shows various modes (1770MHz,-40.56dB; 2260MHz,-15.46dB; 2960MHz,-12.79dB; 4450MHz,-15.29dB). For the far-field radiation pattern, the half-power beamwidth for the E-plane and H-plane were found to b e 99 0 and 63 0 respectively. The antenna directivity estimated using beamwidth information was found to be 20.78/π dBi. From what was observed, in this work, it can be concluded that all the characteristics of the antenna are either directly or indirectly dependent on the dimensions of the antenna.
Radiation Properties Of Microstrip Antenna
isara solutions, 2014
In telecommunication, a microstrip antenna (also known as a printed antenna) usually means an antenna fabricated using photolithographic techniques on a printed circuit board (PCB).[1] It is a kind of internal antenna. They are mostly used at microwave frequencies. An individual microstrip antenna consists of a patch of metal foil of various shapes (a patch antenna) on the surface of a PCB (printed circuit board), with a metal foil ground plane on the other side of the board. Most microstrip antennas consist of multiple patches in a two-dimensional array. The antenna is usually connected to the transmitter or receiver through foil microstrip transmission lines. The radio frequency current is applied (or in receiving antennas the received signal is produced) between the antenna and ground plane. Microstrip antennas have become very popular in recent decades due to their thin planar profile which can be incorporated into the surfaces of consumer products, aircraft and missiles; their ease of fabrication using printed circuit techniques; the ease of integrating the antenna on the same board with the rest of the circuit, and the possibility of adding active devices such as microwave integrated circuits to the antenna itself to make active antennas.
, with emphasis on theoretical and practical design techniques. Available substrate materials are reviewed along with the relation between dielectric constant tolerance and resonant freqnency of microstrip patches. Several theoretical analysis techniques are summarized, including transmission-line and modal-expansion (cavity) techniques as well as numerical methods such as the method of moments and fmite-element techniques. Practical procedures are given for both standard rectangular and circular patches, as well as variations on those designs including circularly polarized microstrip patches. The quality, bandwidth, and efficiency factors of typical patch designs are discussed. Microstrip dipole and conformal antennas are summarized. Finally, critical needs for fnrther research and development for this antenna are identified.
Design of Microstrip Antenna for Wireless Applications
2015
In this thesis, the focus is not in designing any antenna for a particular wireless application but a study on the existing antennas has been made and the methods by which their performance can be improved. The antennas chosen are the standard designs, ones which are most rampantly used in the wireless applications like the Bluetooth, Wi-Fi & Wireless LAN applications in the frequency range of 2.45GHz. An antenna was also designed taking into consideration the GSM band. The bandwidth of the antenna has been given special attention since data rate criterion have to be met apart from the resonant frequency. A circularly polarised antenna was also designed that could be optimised for GPS applications. Further in the thesis a Patch antenna calculator has been designed in MATLAB to reduce the repetitive task of finding the antenna dimension for a rectangular microstrip patch. A GUI has been developed using MATLAB GUIDE tool to provide a user-friendly interface. The calculations are done ...
