Abstract :
A novel feeding technique for dielectric ring resonator antennas, with 2:1 VSWR bandwidth greater than 25% at 5.5 GHz, covering the WLAN upper band is reported in this letter. In order to achieve this wideband characteristic, an L-shaped microstrip monopole is proposed, as both a radiator and a feeding structure. The principle of the wideband characteristics is investigated, with both measured and simulated results of the antenna presented.
