Abstract

In this paper, describes the design of PIFA for PDA which has parasitic patch to expand the impedance bandwidth and miniaturization technique to consider the radiation pattern. To expand the impedance bandwidth, generated resonant frequency of parasitic patch is different from that of main patch. To miniaturize the physical dimension, using the folded edge and rectangular slot. The obtained impedance bandwidth is 9.4% ($2.29GHz{\sim}2.515GHz$) at VSWR${\leqq}$2 and antenna gain is 2dBi within the operating frequency.
