This study presents a novel compact (of volume 0.002 λg 3 ) triple‐band planar inverted‐F antenna (PIFA) for a wireless local area network (WLAN). The upper patch of the proposed antenna is meandered to resonate at WLAN bands and to make it compact. This meandering effect excites its second‐ and third‐order modes along with the fundamental mode to cover all the three WLAN bands. A detailed analysis of the proposed PIFA is done using the theory of characteristic modes and the patch surface current distribution. The parametric study shows that two degrees of freedom are obtained to tune the all frequencies independently by varying the slots' parameters keeping the patch size fixed. In all the bands, it radiates at the broadside direction and provides a sufficient gain. Measured results are also presented here. The simulated and measured results are in agreement.
