Abstract :

A dual band dielectric resonator antenna (DRA) which is compact in size using a conformal feed by a microstrip line is proposed. In this configuration, the dielectric resonator shows the functions of an effective antenna and the feeding through a conformal metal strip is used in the structure to excite a cylindrical DRA with HEM11δ and HEM12δ. By optimizing the proposed structure parameters, the structure resonates at two different frequencies. One is from the DRA and the other from the conformal metal strip. In order to determine the performance of varying design parameters on bandwidth and resonant frequency, the parametric study is carried out using finite element method based simulation software Ansys High Frequency Structure Simulator. The antenna has bandwidth and peak gain of 3.5%, 5dBi and 8.2%, 7dBi at the resonant frequencies of 3.9 GHz and 8.6 GHz, respectively and it finds suitable applications in communication system.
