Planar antenna a network with power supply conductors printed a low loss and pairs of slits incorporated radiating a wide band

摘要

The field of the invention is that of plane array antennas with printed supply conductors coupled to radiating slots and cavities. The aim of the invention is to provide an effective antenna with modest dimensional tolerancing conditions. This aim is achieved with the aid of an antenna module consisting of a support plate 12, an excitation conductor 22, suspended between at least two earth plates 11, 13 drilled with radiating slots 20a, 20b superimposed in pairs, and closed cavities 26 and/or open cavities 27 forming waveguides, aligned ahead of and/or behind respectively at least certain of the said pairs of radiating slots 20a, 20b. The invention finds a preferred application to S or X band microwave frequency antennas. IMAGE
