Patent ID: 7884769

Claim:
A planar antenna assembly for an RF communication module, comprising: a ground plane and a feeding circuit defined onto a face of a printed circuit board, a feed tab and a first shorting tab respectively coupled to said feeding circuit and said ground plane, and a radiating element connected to said feed tab and first shorting tab and in which a slot, including opened and closed ends, is defined, wherein said radiating element includes a first part now located in a first plane approximately perpendicular to said ground plane and in which said slot is defined, the slot being bound by three subparts of the first part of the radiating element, two longest sides of the slot being bound by first and second linear subparts, the first subpart being directly connected to the feed tab and first shorting tab, said feed tab and first shorting tab being parallel and close to the other and connected to the first subpart at a chosen place located at a chosen distance away from said slot opened end to define a chosen input impedance, and a second part being free of any slot extending approximately perpendicularly from said first part to be located in a second plane facing and approximately parallel to said ground plane.
