  • Abstract
    The results of a computational study on the radiation properties of offset prime-focus-reflector antennas are reported. Emphasis is on reducing sidelobes and cross polarization without sacrificing gain. The influence of feed pointing is examined in detail. A simple technique is introduced for determining the feed-pointing direction. This technique yields near-minimum sidelobe levels over practical ranges of feed pointing, with only small penalties in gain and cross polarization.<>
