Abstract
A wideband circularly polarized square slot microstrip antenna with parasitic patch is presented. In this study, the antenna is excited by L-shaped microstrip feed line. The wide axial-radio (AR) and impedance bandwidth are achieved by adjusting the parasitic patch and relative parameters. The proposed antenna has been optimized and fabricated, and the measured results demonstrate a 3-dB AR and 10 dB return loss with bandwidth around 44.9% and 44.4% respectively.
