Abstract The main purpose of this paper is to present a planar inverted-F antenna to be attached to metal containers. The designed PIFA introduce various shapes of slots and meander line for size reduction and loop-shaped stubs for impedance matching. The impedance bandwidth of the PIFA is about 1.4% for VSWR<2 and the maximum gain is about 2.5 dBi.
