Broadband suspended microstrip antenna for circular polarization
FREE-DOWNLOAD VG Kasabegoudar… – Progress In Electromagnetics …, 2009 – Abstract—In this paper we propose a circularly polarized (CP) microstrip antenna on a suspended substrate with a coplanar capacitive feed and a slot within the rectangular patch. The antenna has an axial ratio bandwidth (< 3dB) of 7.1%. The proposed antenna exhibits a much
