Compact dual-band slot antenna for 2.4/5GHz WLAN applications

Abstract

This paper presents a compact dual-band slot antenna for 2.4/5 GHz WLAN applications. The radiating elements of the proposed antenna are composed of a square ring slot and a circular ring slot, operating at 2.4 GHz and 5 GHz bands respectively. The antenna size is very compact (40mm × 40mm × 1mm), and can be integrated easily with other RF front-end circuits. It is demonstrated that the proposed antenna can completely cover the required bandwidths of IEEE 802.11b/g (2.4-2.485 GHz) and IEEE 802.11a (5.15-5.825 GHz) with satisfactory radiation characteristics. Good agreement is achieved between the simulated and measured results.
