A dual‐band planar inverted‐F antenna (PIFA), presented here, covers both 2.4‐ and 5‐GHz bands used in all IEEE 802.11 WLAN standards. Computed and measured return loss and radiation patterns of the antenna are presented and are in reasonable agreement. Experimental results indicate a very wide 32.5% operational bandwidth in the 5‐GHz band.
