A basic antenna (), designed to form a radiating element of an array antenna, includes, superimposed, a planar reflector (), a probe (), and an assembly () of the EBG type by default in the form of a cavity (). The basic antenna () includes a wall enclosure () capable of reflecting the electromagnetic waves at the operating frequency or frequencies of the basic antenna (), the wall enclosure () being an extension in a direction orthogonal to the planar reflector () and simultaneously surrounding only the probe (), the cavity () and the structure (). The one- or two-dimensional array antenna includes a plurality of joined basic antennas () arranged compactly.

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