Patch antenna element

An antenna element for transmission and/or reception of signals within a frequency band comprises a ground plane (4), a patch radiator (2), a connection point (14a) for connection of the antenna element to a feed network and a probe (8a) having two ends. The probe (8a) is located between the ground...

Summary:An antenna element for transmission and/or reception of signals within a frequency band comprises a ground plane (4), a patch radiator (2), a connection point (14a) for connection of the antenna element to a feed network and a probe (8a) having two ends. The probe (8a) is located between the ground plane (4) and the patch radiator (2) and the patch radiator (2) is disposed in a parallel relationship with the ground plane (4) to form a resonant cavity between the patch radiator (4) and the ground plane (2). The antenna element comprises a transmission line (10a) which is disposed in a parallel relationship with the ground plane (4) and the transmission line (10a) is connected to an end (9a) of the probe (8a) and is arranged to have a length such that an impedance at the end (9a) of the probe is transformed. The transmission line (10a) is contained within the resonant cavity between the patch radiator (2) and the ground plane (4).
