Abstract
In this paper, an already designed low profile spiral antenna backed by a partially filled absorber cavity is numerically investigated. The cavity diameter and height were 144mm and 7mm, respectively. Herein, further attempts are made to make the cavity structure even smaller than the aforementioned values while retaining satisfactory CP characteristics. The effects of the cavity height and the width of the absorber ring on the CP performance of the proposed antenna are numerically studied.
