Abstract

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 15 4 mm³. 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 |S ₁₁ | ¿ -10 dB. The radiation patterns, antenna efficiency, and antenna group delay are also measured and discussed. Index Terms-Broadband, impedance bandwidth, inverted-F-L antenna, ultrawideband (UWB).
