Abstract

A miniature independent dual-band hybrid dielectric resonator antenna (DRA) fed by a coplanar waveguide (CPW) inductive slot is proposed. In this configuration, the CPW inductive slot performs the functions of an effective radiator and the feeding structure of the DR. By optimizing the structure parameters, the hybrid structure resonates at two different frequencies independently. One is from the DRA with the broadside patterns and the other from the inductive slot with the dipole-like patterns. In order to determine the performance of varying design parameters on bandwidth and resonance frequency, parametric study is carried out using simulation software HFSS and experimental results. The measured and simulated results show excellent agreement.
