AP0852 Design and Analysis of Elliptical Microstrip Antenna with Partial Ground and Slots Techniques for UWB Applications using CST Studio 2023

Abstract

This study introduced a novel method for modeling, manufacturing and enhancing bandwidth of the elliptical microstrip antenna (EMSA) with the help of Computer Simulation Technology CST tool. The developed EMSA exhibits the following characteristics at its resonant frequency 7.05 GHz, operating bandwidth 5.7% for simulated results and 4.28% for measured, return loss -42dB, impedance matching 50Ω, radiation gain 8.57 dB and Voltage standing wave ratio VSWR 1.016 dB. A drawback of these standard EMSA is their narrow bandwidth. Two approaches have been used to improve bandwidth. First improvement is achieved by using a partial ground plane and the second by slots technique in patch. Bandwidth of 146% and 167% for simulated and measured results, respectively, can be achieved by miniaturization ground plane to partial. BW improvement was significantly achieved by using two slots which at two left- right sides of patch. Bandwidth of 160% and 180% for simulated and measured results respectively.
