Patch antenna element

An antenna element for transmitting and/or receiving signals within a frequency bandwidth includes: a ground plane (4); a patch emitter (2); a connection point (14a) for connecting the antenna element of a power supply network having a terminal impedance; and a probe (8a) having two terminals. The p...

Summary:An antenna element for transmitting and/or receiving signals within a frequency bandwidth includes: a ground plane (4); a patch emitter (2); a connection point (14a) for connecting the antenna element of a power supply network having a terminal impedance; and a probe (8a) having two terminals. The probe (8a) is disposed between the ground plane (4) and the patch emitter (2), and the patch emitter (2) is arranged in parallel with the ground plane (4) in order to form a resonant cavity between the patch emitter (2) and the ground plane (4). The antenna element includes a transmission line (10a) arranged in parallel with the ground plane (4), and the transmission line (10a) is connected to a terminal (9a) of the probe (8a) and has a length such that the impedance is changed at the terminal (9a) of the probe. The transmission line (10a) is included within the resonant cavity range between the patch emitter (2) and the ground plane (4).
