【 摘 要 】

Radiation fields of the offset paraboloidal reflector illuminated by a prime focus feed and tilted feed employing the physical optics method. A set of curves generated by the optimum orientation of the axis of the feed for maximum antenna efficiency as a function of the offset angle β and the half angle α subtended by the reflector at its focus. A comparison on efficiency and side lobe levels is presented for different exiting angles of the feed.
