Design of Ultra-Wideband Dielectric Resonator Antenna using Ceramic-Filled PTFE Composites

Authors: , , ,

Abstract: In this paper, the new dielectric resonator antenna (DRA) is implemented by replacing the traditional dielectric resonator with a new material with low permittivity for ultra-wideband (UWB) application is presented and studied. A hybrid structure DRA was designed with parasitic slot to enhance the impedance bandwidth. The bandwidth met the specification of MB-OFDM for the bandwidth (3.168 GHz - 4.752 GHz). Finally, another antenna structure was designed. By applying the microstrip feed line, UWB and radiation characteristics are achieved. From the measured results, the proposed DRA showed good radiation pattern, high gain, wide bandwidth (3.03 GHz -10.7 GHz) and compact size. The bandwidth met the specification of MB-OFDM (3.168 GHz -10.56 GHz).
