A novel compact monopole antenna for WLAN and WiMAX applications is presented. By properly etching two open-ended inverted L-shaped slots on the radiation patch, three separated resonances with effective bandwidth enhancement can be obtained. The overall dimension of the proposed antenna is only 29 (L) × 10 (W) × 1.6 (H)mm3. Experimental results show that the antenna provides three impedance bandwidth of 80MHz (2.4-2.48GHz), 420MHz (3.28-3.7GHz) and 600MHz (5.23-5.83GHz). Good radiation patterns and applicable gains are also obtained across the operating bands. The proposed antenna is thus suitable for wireless communications systems.
