Abstract
A novel X-band feedhorn has been designed for the DSN 70-meter antennas. The feedhorn is a compound-taper structure consisting of a corrugated flared section (standard JPL 22-dB feedhorn) and a corrugated straight section (stovepipe). This feedhorn is designed to closely initiate the characteristics of the standard feedhorn, while providing the proper phase center location, without adding any significant loss to the system. The use of an existing feedhorn and the ease of manufacturing the stovepipe have resulted in major overall system cost savings.
