Abstract:
The invention relates to an antenna for transmitting or receiving electromagnetic waves at a working frequency fT, that comprises a resonator with a filtering (49) coating that covers the major portion of the upper face of a reflector (22) located inside a cavity (36), the coating (40) being capable of removing all the electromagnetic waves having a frequency fT, and propagating in a direction parallel to the upper face of the reflector, without removing all the electromagnetic waves having a frequency fT and propagating in a direction perpendicular to the upper face of the reflector.
