Abstract
A parabolic cylindrical reflector antenna that comprises two or more antenna feeds each directed towards a parabolic cylindrical reflector, wherein the antenna feeds are positioned in one or more line-arrays parallel to a focal line of the parabolic cylindrical reflector, and the line-array is substantially centered opposing the reflector. The antenna comprises a controller configured to scan along a straight edge of the reflector by electronically adjusting a phase of each of the antenna feeds, thereby changing the incident angle of an energy beam relative to the reflector. The controller is configured to scan along a curved edge of the reflector by moving, using a mechanical positioning mechanism, the antenna feeds in a direction parallel to a directrix of the reflector while maintaining the positioning or by electronically selecting one of two or more parallel line-arrays.
