ABSTRACT:
Disclosed is a source of microwave radiation, namely a source enabling the absorption of multiple reflections for the illuminating of a lens in order to form an electronic sweeping antenna. The source includes a layered arrangement of elementary illuminators in a direction substantially parallel to the electrical field of the microwave energy transmitted. In one embodiment, each elementary illuminator has the following successively, in the direction of propagation of the energy: a plane forming a short circuit; a plane forming an incidence filter, parallel to the above plane, located at a distance from the above plane of the order of half of a wavelength, including two tracks parallel to each other and perpendicular to the electrical field between which resistive elements are connected; and, a plane bearing a rdiating element of the snake line type, extending in a direction substantially normal to the electrical field. The illuminator and the filter are such that the filter at least partially absorbs the microwave energy received with a non-zero angle of incidence.
