Abstract
A new microwave horn suitable for use in selected DSN antenna feed applications is described. The new horn uses two hybrid modes propagating within corrugated conical waveguide. Expected aperture efficiency improvement, when feeding DSN reflector antennas, as well as bandwidth information is provided. It is concluded that the new horn provides 0.36 dB gain improvement when feeding a symmetrical Cassegrain antenna; it is estimated that 0.29 dB improvement is available when feeding an asymmetric system such as the DSN 64-m antenna tricone configuration. Bandwidth considerations suggest application at X-band (8.4 to 8.5 GHz) is straightforward; the S-band uplink and downlink bands cannot both be covered at this time.
