Cylindrical Dielectric Resonator Antenna for SHF Band Application

In this paper, an embedded cylindrical dielectric resonator antenna (CDRA) is presented .The antenna, excited by a coaxial feeder is composed of one host cylinder made from ceramic, with a constant ? r1 =36.7 operating at a frequency of 1.96 GHz; which excites the HEM 11? mode and the embedded cylindrical element with radius a 2 and permittivity ? r2 . In order to get a wideband antenna, that can offer multi-resonant frequencies used for SHF band, parameters retune son the radius and permittivity of additional element are presented. The study shows briefly, broadband dielectric resonator antennas (DRAs) design using HFSS simulator tool, based on finite element method.
