Abstract
In this paper, a compact dielectric resonator antenna (DRA) with band-notched
characteristics for ultra-wideband applications is presented. A comprehensive parametric study was
carried out using CST Microwave Studio Suite TM 2011 to analyze and optimize the characteristics of
the proposed antenna. Three shapes for the coupling slot were investigated. Simulation results show
that the proposed DRA had a −10 dB impedance bandwidth of 23% from 9.97 GHz to 12.558 GHz, and a
maximum gain of 7.23 dBi. The antenna had a notched band centered at 10.57 GHz, which increased the
reflection coefficient by 23.5 dB, and reduced the gain by 6.12 dB. The optimized designs were verified
by experimental tests on fabricated samples.
