Abstract :
This paper describes the design of a dual frequency corrugated horn. The center operating frequencies are 52.5 GHz and 118.75 GHz. This feed is used to illuminate an offset reflector. Return loss and cross polarization requirements were taken into account. In addition, the far field radiation patterns at both operating frequencies have to overlap.
