A novel design of planar balance‐shaped slot antenna suitable for triple‐band WLAN/WiMAX applications is proposed in this article. It consists of a slotted ground plane, an FR4 substrate, and an L‐shaped microstrip feedline. The radiating element of the proposed antenna is composed of a horizontal H‐shaped slot and an M‐shaped slot, like a balance. The horizontal H‐shaped slot mainly contributes to the 2.4‐ and 3.4‐GHz resonant modes while the resonant modes at 5.4 and 5.8 GHz are generated by the M‐shaped slot. The overall size of the proposed antenna is only 30 × 28 mm 2 , very compact, making it easy to be integrated with other RF front‐end circuits. The measured results agree well with the simulated ones and demonstrate that the antenna has a triple‐band characteristic entirely covering the 2.4/5.2/5.8‐GHz WLAN and 2.5/3.5/5.5‐GHz WiMAX operating bands. Furthermore, monopole‐like radiation patterns with acceptable gains make it a good candidate as an internal antenna for WLAN/WiMAX applications. © 2016 Wiley Periodicals, Inc.
