Antenna assembly
First Claim
1. An antenna assembly comprising a printed circuit board having on one face various electrical components and on the other face a ground plane, said printed circuit board including an aperture, and an antenna structure comprising:
- a conductive ground plane element having peripheral attachment lugs overlapping the edge of the aperture, a connecting element integral with the ground plane element and extending from the ground plane element through the said aperture, a radiator element integral with the connecting element and extending generally parallel and within the area of the ground plane element, and an antenna feed element which extends from the radiator element through said aperture to said one face of the printed circuit board.
