ABSTRACT:
A low profile Planar Inverted-F Antenna (PIFA) comprises a radiating strip, an inductive tuning portion, a vertical feed portion, and a retracted ground plane. The radiating strip is approximately parallel to the ground plane and is suspended above the ground plane by the feed element at a certain distance. Further, the radiating strip, in part or entirely, overhangs the ground plane. In this way, the radiating strip may be suspended very close to the ground plane, but yet exhibits a large bandwidth.
