A circular polarization antenna with square ring slot loaded on ground plane

Muhammad Asad Rahman, Eisuke Nishiyama, Ichihiko Toyoda

Abstract

A new circular polarization microstrip antenna having a defected ground plane is presented in this paper. A defect on the ground plane is introduced by inserting a square ring slot just below one of the top corners of the patch. The inserted slot on the ground creates a perturbation in the patch as like as conventional perturbed circular polarization antennas. The measured 3-dB axial ratio bandwidth was 1.26% with a gain of around 6.1 dBic.
