Abstract
In the past, parabolic offset reflector antennas were fed a signal through a corrugated horn in order to optimize field distribution and polarization at the reflector. It has been found that cost savings and other advantages are realized by using an array of radiating patches. The geometrical placement of the radiating patches and the power distribution to each patch is arranged such that radiated energy from the patches sums at the reflector surface to produce the predetermined field distribution and polarization.
