Abstract
Wireless Technologies is one of the main and very vast areas of research in the world of communication system. The study of communication is incomplete without understanding of the operation and fabrication of antenna. For which we are proposed a simple micro strip patch antenna using micro strip feeding technique at low frequency 2.9 GHz, 3.1 GHz, 2.7 GHz and 2.8 GHz. This is obtained by embedding a rectangular metal patch antenna in the square slot. This paper shows the design analysis of square micro strip patch antenna. The MPA is designed by using low cost FR-4 substrate with dielectric constant of 4.4, and a loss tangent of 0.019 and with a thickness (h) of 1.6mm. We are using CST Studio for simulation and the performance such as Radiation pattern, Radiation efficiency, Directivity, VSWR, Gain, Return loss are obtained. In our proposed antenna design has a good return loss of -24 dB, -14 dB, -24.5 dB and -15.5 dB, VSWR 1.4, 1, 1.12 and 1.4 and Directivity of 4.1, 1.8, 3.7 and 3.2 at interest of frequency 2.9 GHz, 3.1 GHz, 2.7 GHz and 2.8 GHz respectively for wireless communication.
