Abstract

A novel wideband hybrid dielectric resonator antenna structure comprises a rectangular dielectric resonator (DR) and a coplanar waveguide (CPW) inductive slot is proposed. In this configuration, the CPW inductive slot simultaneously acts as an effective radiator and the feeding structure of the DR. Dual resonances of the two radiators are merged to extend the antenna´s bandwidth. A parametric study is performed to optimize the antenna performance and a prototype for 5-GHz WLAN application has been built and tested.
