<p>An increased bandwidth patch antenna (300) which includes first and second arms (308, 312) spaced by an air gap. The first and second arms (308, 312) are electrically connected by a bridge (324). A ground plane (316), which is approximately parallel to the first and second arms (308, 312) is separated from the first and second arms by a dielectric substrate (320). In one embodiment of the present invention, the first arm (308) is a radiating arm and the second arm (312) is a tuning arm. By varying the length of the tuning arm, the bandwidth of the antenna is increased. The second arm (312), which also acts as a parasitic arm of the first arm (308), increases the gain of the antenna (300). A signal unit (332) is electrically coupled to the bridge (324). The signal unit (332) transmits and/or receives signals having a selected frequency band. The antenna (300) resonates at the selected frequency band.</p> |
