Arrangement relating to reflector antennas |
摘要 |
The present invention relates to the field of arrangements in reflector antennas, and in particular to that part of this field that concerns reflector antennas that include subreflectors. The invention is concerned chiefly with an improved subreflector (5b) which when used in a reflector antenna (1) enables the antenna to obtain a radiation diagram with high suppression of side lobes in both the H-plane and the E-plane. The reflective structure of the subreflector (5b) includes at least two mutually different geometries (15, 17) that have been configured specifically to obtain radiation diagrams with good suppression of side lobes in both the E-plane and the H-plane.
