DUAL-WIDEBAND MONOPOLE LOADED WITH SPLIT RING FOR WLAN APPLICATION

This paper presents a novel monopole antenna which uses split ring loading in order to achieve a dual-wideband operation for WLAN (2.4/5.2/5.8GHz) application. By adjusting the split ring position and its natural resonant frequency, the proposed antenna can produce more than 1GHz wideband match in the 5GHz band. According to the measured results, the bandwidth with re∞ection coe-cient less than i10dB is about 715 and 1017MHz in the two bands. Good radiation patterns are also achieved. The dimensions of the monopole loaded with split ring are 27.2mm £ 16.2mm £ 1mm, which is suitable for a hallway antenna or ceiling mount antenna of WLAN application.
