Abstract
A three-horn microwave feed produces a near ideal aperture width ratio of 2:1 for the difference and sum modes of aperture illumination. Three horns are utilized, each of which supports propagation of at least two modes. Sum and difference components are present in all three horns in response to signals applied to both sum and difference ports of the feed and sum illumination components are present in all three horns in response to signals applied to only the sum port of the feed.
