Patent ID: 7265724

Claim:
An antenna radiator assembly comprising: a circuit board formed with electrical conductors thereon, at least one of the electrical conductors being coupled to a feed point, the circuit board having a ground plane formed from at least one conductive sheet; a tuning plate formed from part of the conductive sheet; a parasitic tuning line, a switching unit selectively electrically coupling the tuning plate to the tuning line; at least one antenna radiator element spaced from said circuit board and coupled to the feed point, and when viewed in plan view there is an overlapping area where an overlapping surface area of the antenna radiator element overlaps an overlapping surface area of the circuit board thereby forming a sandwiched dielectric region therebetween, the sandwiched dielectric region providing capacitive coupling of the tuning plate and the antenna radiator element; and a ground connector inductively coupling the antenna radiator element to the ground plane, wherein the tuning plate is disposed in the overlapping surface area of the circuit board.
