Abstract
In this article, a planar inverted‐FF antenna with suspended rectangular feeding mechanism is presented for lower band ultra‐wideband and IEEE 802.11a wireless local area network applications. By manipulating the optimum strong electromagnetic coupling distance between driven and parasitic F‐shaped radiators on a small ground plane, two closely separate resonances can be merged to form a wide impedance bandwidth of 73.7% (3.0–6.5 GHz) at |S~11~| < −10 dB. The overall occupied antenna volume is 30 × 15 × 3 mm^3^ to satisfy the size requirement of modern wireless devices. The impact of the different antenna geometry parameters on the antenna performance is studied. The corresponding measured radiation patterns, gains and group delays are given to fully characterize the performance of this antenna. © 2011 Wiley Periodicals, Inc.
