Abstract :
The application of axially displaced ellipse antenna elements in a multibeam antenna system is recommended. It is shown that in an axially displaced ellipse antenna, a simultaneous lateral shift of both the feed and subreflector results in much more beam tilting than does a shift of the feed, alone. The results of calculations and comparisons with known data are given.
