Abstract
In support of the Mariner 1973 X-band experiment, it is necessary to implement a dual-frequency microwave feed system for the DSS 14 64-meter-diameter antenna. To fulfill this requirement, a particularly attractive approach, the reflex feed system, is being implemented. The reflex feed configuration and its calculated aperture efficiency performance were described in a previous reporting. Additionally, calculated radio frequency (RF) power dissipation data for the reflex feed were reported. In this article, two questions are analyzed: (1) the S-band effects of possible buckling of the dichroic flat plate caused by RF and solar heating, and (2) the effect of subreflector backscatter on the S-band focus characteristics of the antenna.
