Abstract :
A pyramidal horn antenna excited with parasitic dielectric resonator (DR) antenna for use at Ka-band frequencies is proposed. This antenna been divided into two parts, microstrip-fed rectangular slot DR antenna and a pyramidal horn. DR antenna consists of five identical cylindrical parasitic DR fed by a microstrip feedline through a coupling rectangular slot in the ground plane between them. It is designed to parasitic type for high gain, high isolation and wideband characteristics. Simulated result shows the antenna produce high gain that is larger than 19.8 dB. CST simulation results of the electrical performance for pyramidal horn antenna operating at 38 GHz are presented.
