DUAL-WIDEBAND RECTANGULAR DIELECTRIC RESONATOR ANTENNA FOR WLAN COMMUNICATIONS

摘要

A dual and wideband single-element rectangular dielectric resonator antenna (DRA) excited by a microstrip aperture is investigated experimentally, It provides two passbands in the ranges of 2.21-2.855 GHz and 4.385-5.455 GHz, which are popular bands for wireless local-area networks (WLANs). The return loss, antenna gain, and radiation patterns of the proposed configuration are measured.
