摘要: In this paper, a numerical study of new ultra wideband (UWB) dielectric resonator antenna (DRA) is presented. The proposed structure consists two stacked resonators excited by rectangular patch and operated from 3GHz to 11GHz (an impedance bandwidth 115%), covering the full UWB spectrum. analysis carried out using Finite Difierence Time Domain (FDTD) method commercial electromagnetic simulators. results are given compared in terms re∞ection coe-cients, radiation pattern gain. computed FDTD good agreement with those simulations.
