Abstract :
A differential-feeding UWB planar inverted-F antenna (PIFA) is proposed and investigated. The good matching of antenna depends on the matching between the feeding network and the radiation element, as well as the inherent matching of feeding network. In this work, the PIFA antenna with good impedance matching is designed firstly, and the differential-feeding technique is employed to achieve UWB performance. A prototype of this UWB antenna is fabricated and measured. The experimental results indicate that the impedance bandwidth (SWR<;2) of the PIFA is about 93.1% (3.1GHz ~ 8.5 GHz). In addition, the symmetric and stable radiation patterns are observed within the wide band, demonstrating the validity of the design strategies and the potential application of this UWB PIFA antenna.
