Abstract :
Excitation of the circularly polarized (CP) aperture-coupled hemispherical dielectric resonator antenna (DRA) using a parasitic patch is studied. The analysis consists of two parts, namely the DRA with a parasitic patch and the microstrip feed line. In this paper, theoretical results on the return loss and radiation field pattern are presented.
