Enhanced-Gain Dielectric Resonator Antenna Based on the Combination of Higher-Order Modes

Abstract

The combination of two higher-order hybrid electromagnetic modes ( HEM133 and HEM123) in a simple cylindrical dielectric resonator is exploited in the presented letter to enhance antenna gain. Both modes were excited by the same feeding aperture in the ground plane of a microstrip line. A linearly polarized, broadside radiation pattern with maximum realized… (More)
