Abstract :
The design of a high-efficiency spline-profile smooth-walled circular horn covering the 34-38 GHz band is described. This horn is proposed for an array feed for the RATAN-600 radio telescope. Across the band the horn has a predicted aperture efficiency >96% and a cross-polarization < -23 dB.
