摘要

This study presents a novel, simple technique to improve the Front-To-Back Ratio (FTBR) of a microstrip patch antenna. The radiation in the backward direction of the microstrip patch antenna is reduced by introducing two rod shaped parasitic elements on either side of the patch antenna, designed for 1.77GHz. The simulation results obtained, by using CST Microwave Studio 2016, show that the back lobe can be reduced by more than 15dB, over and above the plain microstrip antenna. The return loss also gets reduced. Half Power Beamwidth (HPBW), bandwidth and antenna efficiency are also increased.
