Analysis of the radiation pattern of a straight-through array excited by a highly directional feed
Abstract
The dependence of the radiation pattern of a straight-through antenna array excited by a highly directional feed on the geometric characteristics of the feed and the array itself is defined. It is shown that the main lobe is formed in accordance with the focal distance, the dimensions, the aperture shape, and the amplitude distribution of the feed array. Pattern distortions and energy losses can be reduced by increasing the aperture size and the number of radiating elements of the straight-through array. The use of a counterreflector feed for the excitation of large-aperture reflector antennas or reflection-type and straight-through phased arrays is considered as an example.
