A planar inverted-F-L antenna (PIFLA) with a broadband rectangular feeding structure is proposed for lower-band ultrawideband (UWB) applications. This antenna is constructed from a driven F-shaped element and a parasitic L-shaped element. Both patches are inverted and aligned face to face over a finite ground plane; the optimized dimensions of this antenna are 30 x 15 x mm(3). The realized antenna achieves a gain between 2.5 and 4.7 dBi over a 66.6% impedance bandwidth (on the interval 2.8-5.6 GHz) for vertical bar S(11)vertical bar <= -10 dB. The radiation patterns, antenna efficiency, and antenna group delay are also measured and discussed.
