Abstract
A basic antenna (2), designed to form a radiating element of an array antenna, includes, superimposed, a planar reflector (4), a probe (6), and an assembly (8) of the EBG type by default in the form of a cavity (16). The basic antenna (2) includes a wall enclosure (10) capable of reflecting the electromagnetic waves at the operating frequency or frequencies of the basic antenna (2), the wall enclosure (10) being an extension in a direction orthogonal to the planar reflector (4) and simultaneously surrounding only the probe (6), the cavity (16) and the structure (14).The one- or two-dimensional array antenna includes a plurality of joined basic antennas (2) arranged compactly.
