In this paper rectangular dielectric resonator antennas (RDRAs) which providing circular polarization (CP) using single probe feeds are studied. A new technique for CP achievement is presented. This technique proposed that by modifying the RDRAs in suitable way, the fundamental mode of conventional rectangular DRA splits into two near-degenerate orthogonal(More)
In this paper, a low profile dual loop wire antenna over an EBG surface is investigated for wideband circular polarization. A wideband mushroom-like EBG surface is used as the antenna ground plane. In comparison with a PEC ground plane, design of the antenna above an EBG ground plane results in 60% reduction of the structure thickness. It is shown that the(More)
