Abstract
This elementary antenna includes a cavity delimited by front and rear faces and side walls, the front face being provided with first and second slots arranged in a cross, so that, when the cavity operates in a TE210 mode, a wave polarized perpendicularly to the first slot is emitted and when the cavity operates in a TE120 mode, a wave polarized perpendicularly to the second slot is emitted. This elementary antenna is characterized in that the rear face is brought to a reference electric potential, and in that the elementary antenna includes an excitation device, such as a metallized via, capable of exciting the front face through the cavity, the excitation device exciting the front face at a plurality of excitation points, distributed over the front face and presenting a common predefined impedance.
