Abstract
A Planar Inverted F Antenna (PIFA) is disclosed comprising a radiator assembly positioned in the interior of a lower Radome member. An upper Radome member is placed over the radiator assembly with the upper Radome member and the lower Radome member fully enclosing the radiator assembly. The radiator assembly is held to the upper and lower Radome members by means of three dielectric blocks on each member. The radiator assembly comprises: (1) two radiating elements placed on the opposite sides of common ground plane; (2) two separate shorting strips extending between one end of each radiating element and one end of common ground plane; (3) a common feed conductor in the form of a single strip connecting one edge of each radiating element and the common feed conductor which has a disc-shaped portion with an opening formed therein. A ground tab is formed as an extension of the common ground plane. A hollow cylindrical structure formed as an outward extension of the lower Radome member constitutes the embedded (built-in) connector for the PIFA. A metal rod is inserted through the opening in the disc-shaped portion and protrudes into the hollow cylindrical structure to serve as the feed …
