Rectangular dielectric resonator antenna on a conductor-backed co-planar waveguide

Abstract

In this paper, we present an effective excitation of a rectangular dielectric resonator antenna (DRA) with a conductor-backed co-planar waveguide (CB-CPW). The radiation and resonance characteristics are found to vary, depending on the orientation of the DR oil the coplanar feed line. The effect of finite and infinite ground planes of CB-CPW on the radiation characteristics of the rectangular DRA is studied. The orientation and position of the DR are optimized for maximum gain and bandwidth. The optimized antenna geometry offers similar to 10.46 dBi gain and 7.5% bandwidth with low cross-polar radiation characteristics.
