Abstract

A filtering hemisphere dielectric resonator (DR) antenna (DRA) is presented. It consists of a conventional hemisphere DR, a ladder-like feeding line, and three slots etched in the ground. In this antenna, three modes, which are the fundamental TE₁₁₁ DR mode and two slot modes are excited simultaneously. By making use of the mode-cancelling effect, two independently tunable radiation nulls are obtained beside the passband, producing filtering responses. Simulated results show that our antenna has a -10-dB impedance bandwidth of 17.4%, a gain of ~5.7 dBi, and a suppression level of 19 dB.
