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.
