Abstract
This article discusses the feed system configuration, RF optics design and predicted gain and noise temperature performance of the DSN 26 meter antenna S-/X-Band upgrade project. A previously developed and demonstrated dual band feed system employing separately located feeds, combined in a reflex-dichroic reflector arrangement, has been adapted to a particularly compact overall design. Special design techniques to minimize aperture blockage and then evaluate resultant performance are discussed in detail. Final predicted antenna gain and noise temperature performance values are given.
