A novel multiband rhombic slot antenna with a truncated corner is proposed for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications simultaneously. By introducing a pair of straight strips and two etched ∩‐shaped slots, the proposed antenna can operate in multibands. The prototype of the proposed antenna has been successfully constructed and tested. The 10 dB return loss bandwidths of them are 550 MHz (3.15–3.70 GHz) and 920 MHz (5.05–5.97 GHz), respectively, which can cover both the WLAN bands (5.15–5.35 GHz and 5.725–5.825 GHz) and the WiMAX bands (3.4–3.6 GHz and 5.25–5.85 GHz). In addition, good monopole‐like radiation characteristics with sufficient antenna gains are obtained over the operating bands. © 2012 Wiley Periodicals, Inc.
