Abstract

A broadband compact CPW-fed antenna with a reactive metamaterial-inspired loading is proposed for WLAN/WiMAX applications. The L-shaped antenna exhibits the upper WLAN band and the metamaterial-inspired reactive loading creates a broad operating band, which covers the lower WLAN band and WiMAX band, successfully. The measurement results show very good gain and broad impedance bandwidth. The bandwidths of the proposed antenna are 1.85 GHz (2.35 - 4.20 GHz) and 1.37 GHz (5.11- 6.47 GHz), and provide sufficient coverage for WLAN band (2.4/5.2/5.8) and WiMAX band (2.5/3.5/5.5).
