Abstract
A multiple beam array antenna that is designed with an aperture shape which conforms to the particular coverage area to which the antenna is directed. The antenna consists of individual horn antennas (20) that are nested together to form the array (14). The outer walls (50) of the peripherally disposed horn antennas (40) are individually shaped such that the combined shape of the outer walls (50) of the peripherally disposed horn antennas (40) determine the perimeter shape of the aperture (12) of the horn array (14). Where the desired coverage area is circular, elliptical or irregularly shaped, the shape of the perimeter of the aperture (12) of the horn array (14) is similarly circular, elliptical or irregularly shaped, respectively.
