A hybrid resonator antenna suitable for wireless communication applications at 1.9 and 2.45 GHz

This letter presents a compact dual-frequency hybrid resonator antenna suitable for wireless communication applications at 1.9 and 2.45 GHz. The proposed antenna utilizes a combination of a disk dielectric resonator (DR) and a microstrip fed rectangular slot, and a circular metal sheet partially covers the top of the DR. The measured results validate the proposed design.
