Patent ID: 7843397

Claim:
A planar antenna assembly for use in two different frequency bands, the planar antenna assembly comprising: a printed circuit board having a ground plane and RF circuitry thereon; a patch antenna spaced from the ground plane, the patch antenna not having any slot; a feed for coupling the patch antenna to the RF circuitry, the feed comprising components that are physically attached to a main surface of the patch antenna, the components for reactively tuning the patch antenna by tuning a first frequency inductively and a second frequency capacitively, the first frequency being lower than the second frequency, wherein the components comprise an inductive element and a capacitive element electrically connected to the patch antenna at two different points, the inductive element being electrically connected between the two points and the capacitive element being electrically connected between the two points in parallel with the inductive element; and a shorting tab electrically connected between the ground plane and the patch antenna, wherein the shorting tab electrically connects to the patch antenna adjacent to a connection point of the feed, the shorting tab performing an impedance transformation.
