Abstract :
In this paper the free-space performance of a commonly used planar inverted-F antenna (PIFA) on top of various rectangular ground planes is studied by simulations. Special attention is given to impedance bandwidth and antenna efficiency. The study is carried out for five frequency bands; CDMA800, GSM900, GSM1800, GSM1900 and UMTS. Optimal ground plane dimensions for each frequency band are given and performance results for selected bands are shown as a function of the ground plane dimensions. Finally effect of the ground plane size on the performances of multiband antennas comprised of different combinations of selected frequency bands are discussed.
