Gain factor of horn array feed offset parabolic cylindrical reflector antenna for spatial power combining

Z. M. Xie, Runxuan Zhang

Abstract

Abstract A study on the horn array feeding offset parabolic cylindrical reflector antenna for spatial power combining is presented. The calculations based on the aperture integral method are agreed well with the measurements. The relationship between the gain factor and the dimensions of the antenna is analyzed. The optimal dimensions and orientation of the feeding horn as well as the optimal spread angle of the reflector are given. It is revealed that the gain factor of the antenna with anE_plane array feed is higher than that of the antenna with anH_plane array feed. © 2010 Wiley Periodicals, Inc.
