Abstract
An inverted F antenna with integrated shield is constructed from an electrically conducting sheet that is folded into a shape that provides both a shield can covers an RF module of circuit and an inverted F antenna such that shield can functions also as a ground plane for the antenna. In a pre-folded state the sheet has a shield can portion and a radiating element portion that are connected to each other by a ground feed line that bridges the shield can portion and radiating element portion. The shield can portion preferably includes a plurality of walls that are foldable along respective folds. The radiating element portion preferably includes a plurality of edges and a signal feed line extending from a first one of the plurality of edges. The ground feed line extends from a second one of said plurality of edges. When the sheet is folded, the radiating element portion is suspended over the shield can portion and is substantially fixed with respect to the shield can portion by the ground feed line and the signal feed line.
