In this paper, we present a new compact Planar Inverted F Antenna (PIFA) applicable to PCS system. The principle aim in design is to broaden the bandwidth. To overcome the narrow bandwidth characteristic, that is typical of a patch antenna, a type of tapered patch is employed. In specific case, bandwidth of about 15.2% was achieved experimentally. And when the tapered type PIFA was applied to a specially designed mobile phone structure, the Specific Absorption Rate (SAR) value was less by 40% than that of the conventional structure.
