Novel Design of Annular-ring Slot Antenna for WLAN WiMAX Applications

Abstract

In this paper, we present a new design of annular-ring slot antenna for WLAN/WiMAX applications. The radiating element of the proposed antenna is composed of two annular-ring slots. The antenna has a compact size of 40mm×40mm, which can be integrated easily with other RF front-end circuits. The simulated results show that the proposed antenna has a triple-band characteristic at 2.41GHz~2.62GHz, 3.31GHz~3.75GHz and 4.95GHz~5.40GHz. It also enjoys advantages such as low profile, low cost, high gain and satisfactory radiation characteristics.
