Abstract
This paper provides an optimized design of feed-source based on four combination waveguides distributed in rectangle for W-band reflector antenna systems. The optimized waveguide feed-source contains a coupled retracted structure in front of the waveguides skillfully, which is very important in eliminating source pattern notches generated by four combination waveguides distributed in rectangle. The optimized feed-source pattern is of -10dB beam-width 152° in E-plane and 116° in H-plane.
