Abstract

The antenna array preferably consists of a plurality of slotted wave guide microwave signal radiating elements positioned to directly radiate separate beams of microwave energy at different azimuth angles to a common horizontally aligned cylinder sector reflector, the radiating elements being operable to primarily determine the direction and shape of the resultant reflected beams in azimuth and the reflector being operable to primarily determine the elevation patterns of the resultant reflected beams.
