Abstract

The present paper is devoted to the enhancement of the impedance bandwidth of a coaxial probe fed rectangular dielectric resonator antenna (RDRA) by introducing an air gap between the rectangular dielectric resonator (RDR) and the ground plane. An impedance bandwidth of approximately 31% is obtained when the coaxial probe only touches the bottom surface of the RDR. Good agreement between finite difference time domain (FDTD) and high frequency structure simulator (HFSS) results is obtained.
