Technique for reducing near-in sidelobes of an offset antenna

摘要

The present invention relates to technique for reducing near-in sidelobes of an offset antenna. The method comprises positioning at least one piece of microwave absorbing material on a sector of the edge of the reflecting surface of the offset main reflector closest to the focal point of the antenna. The material is positioned on the portion of the edge of the reflecting surface nearest the focal point of the main reflector in such a manner as to achieve substantial selective reduction of the near-in sidelobes generated by the antenna.
