Abstract
A Planar Inverted F Antenna (PIFA) is disclosed comprising a radiating element and a ground plane positioned on a bottom cover. A Radome is positioned over the radiating element and the ground plane with the bottom cover and the Radome enclosing the radiating element and the ground plane. The ground plane is positioned below the radiating element and a conductive shorting strip extends between one end of the radiating element and one end of the ground plane. A feed lead extends from one side of the radiating element and has a base portion which protrudes outwardly of the Radome for connection to the center conductor of a RF power feeding cable. The radiating element includes a first horizontally disposed portion, a second horizontally disposed portion, and a substantially vertically disposed portion extending therebetween. The first substantially vertically disposed portion of the radiating element functions as a first capacitive loading plate with the second horizontally disposed portion of the radiating element functioning as a second capacitive loading plate. A dielectric block is positioned between the second horizontally disposed portion of the radiating element for providing dielectric loading to the radiating element.
