Abstract

In some applications the electromagnetic waves radiating from or being received by an antenna are obstructed by some mechanical structure. If the structure is part of or close to an antenna, the obstruction may represent aperture blockage causing increased sidelobes and reduced gain of the antenna. For example, the blocking structures can be struts or masts supporting the feed in reflectarrays or in reflectors. Usually in antennas, the direction of the incident wave is known, so the struts can be designed to reduce the blockage for a given direction of incidence.
