An increased bandwidth patch antenna which includes first and second arms spaced by an air gap. The first and second arms are electrically connected by a bridge. A ground plane, which is approximately parallel to the first and second arms, is separated from the first and second arms by a dielectric substrate. In one embodiment of the present invention, the first arm is a radiating arm and the second arm is a tuning arm. By varying the length of the tuning arm, the bandwidth of the antenna is increased. The second arm, which also acts as a parasitic arm of the first arm, increases the gain of the antenna. A signal unit is electrically coupled to the bridge. The signal unit transmits and/or receives signals having a selected frequency band. The antenna resonates at the selected frequency band. |
