摘要：

To achieve dual-frequency operation, a new design concept that utilizes a hybrid structure that includes a dielectric resonator antenna (DRA) and a slot radiating resonator, was investigated experimentally. The proposed structure consists of a DRA, a circular slot and an eccentric ring slot on a co-plane ground plane. This arrangement can be described as two cascaded resonant circuits that resonate at two different frequencies. One is from the DRA and the other from the ring slot. Based on the proposed design concept, a number of phototypes have been successfully designed, fabricated and tested. The measured results have demonstrated the validity of the proposed design.
