Abstract
A dual-band feed for the Deep Space Network (DSN) large array is described. The feed covers the 8- to 9-GHz and 30- to 40-GHz bands using a coaxial configuration. A saturated corrugated horn controls the radiation pattern in the lowfrequency band, and a dielectric rod is used as the radiator in the high-frequency band. The major requirements for the feed are described, and a summary of several possible feed configurations is presented. Next, the analysis tools used to perform the design are described. The bulk of the article covers the mechanical configuration of the feed, measured radiation patterns, and measured scattering parameters. Finally, the predicted performance of the feed–reflector antenna combination is presented.
