Patent ID: 7786941

Claim:
An antenna module, comprising: a first radiation conductor, substantially as invert L-shape, having a bottom side; a second radiation conductor, further comprising a coupled portion and an extending portion, wherein one terminal of the coupled portion is near the bottom side of the first radiation conductor with a gap and the other terminal of the coupled portion is connected to the extending portion; a short-circuit element having a terminal connected to a terminal of the extending portion different from the terminal connected with the coupled portion; a ground plane, connected to the other terminal of the short-circuit element; a feed-in cable further comprising a centre conductor and an external conductor, wherein the centre conductor is connected to the first radiation conductor and the external conductor is connected to the ground plane; and a spurious radiation conductor, connected to a terminal of an extending terminal different from the terminal connected with the coupled portion, further comprising a spurious radiation plate, a first radiation piece and a second radiation piece within the two sides of the second radiation conductor, wherein a terminal of the first radiation piece is in parallel with a terminal of the second radiation piece with a gap.
