Abstract :
A technique is discussed for moving the phase center of a corrugated feedhorn without any significant degradation in its other major characteristics. Based on this technique, an X-band feedhorn has been designed for use in NASA´s 70-meter antennas. The feedhorn is a compound-taper structure consisting of a conventional corrugated flared section (a standard 22-dB feedhorn) and a corrugated straight section (here called stovepipe).<>
