Abstract
This paper presents a single aperture multibeam spatial power combining system that can support two separate polarizations. A Rotman lens is used as the power dividing network, which also has the ability to scan the beam over discrete angles. 1/spl times/9 dual polarized array was designed to demonstrate the beam steering in azimuth plane. The entire system is designed for the Ka band, with a center frequency of 32.5 GHz. The use of MMIC amplifiers allow for high power multibeam capabilities. Through simulations and measurements, a /spl plusmn/30 degree scan range was achieved for the horizontal and vertical polarizations.
