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 on 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 ∼10.46 dBi gain and 7.5% bandwidth with low cross-polar radiation characteristics. © 2005 Wiley Periodicals, Inc.
