Circular Polarized Elliptical Dielectric Resonator Antenna Sub Array Fed by Hybrid-Ring Feeding Network

Abstract

In this paper we study the hybrid-ring feeding network, which has the advantages of linear phase difference across a wide impedance bandwidth. It is of practical interest to investigate the performance of hybrid ring feeding network in sequential feed circularly polarized dielectric resonator antenna (CP DRA) sub-array. In this paper, the performance of CP DRA sub-arrays excited by hybrid-ring feeding network is presented
