ABSTRACT: This paper describes the design
and simulation by High Frequency Structure Simulator (HFSS) of a probe-fed Planar
Inverted-F Antenna (PIFA) for the Ultra Wide Band (UWB) personal area networks.
The slim antenna presents a height of 2 mm and a bandwidth of more than 766 MHz. This bandwidth was improved by etching a U-slot
in the antenna patch. The bandwidth offered then by the antenna is 839 MHz around
the resonant frequency of 9 GHz. The improvement of bandwidth was accompanied by
decreasing in gain and radiation efficiency. The simulation allowed the characterization
of the designed antenna and the computing of different antenna parameters like S11 parameter, resonant frequency, bandwidth, radiation efficiency, gain and diagram
pattern. The results are very interesting and respect the Federal Communications
Commission (FCC) requirements.
