Abstract

In this paper, a L-circularly polarized aperture-coupled feeding microstrip patch antenna array with a high gain and a good axial ratio is presented. It´s suitable for operation in portable satellite communications stations. The microstrip line feeding of circular microstrip patch antenna is applied and the coupling aperture is the cross-shaped aperture. The proposed antenna array covers 29.4-31.0 GHz at the Ka band. Details of the antenna array design along with simulated results are presented and discussed.
