Abstract

This paper presents an analysis on aperture slot distribution of circularly polarised radial line slot array (RLSA) antennas. Two circularly polarised RLSA (CP-RLSA) antennas were designed with two different layout of slots on the antenna aperture. The distributions were optimised by controlling the slot surface density. Numerical results of these two different aperture distributions are presented and compared. A significant improvement has been made in broadside directivity. One distribution has achieved a peak directivity of 22.7 dBi as compared to the directivity of 19.6 dBi achieved with the other distribution.
