Novel Model

A sun outage is an interruption or distortion of satellite communication signals caused by interference from solar radiation. There is a serious interference to satellite communication services in a special period of time. In the present paper, a novel model for predicting sun outage that is effective and can greatly improve accuracy and precision of sun outage prediction of earth station in satellite communication is presented.

A design for Ka-band satellite communication antenna in earth station is introduced. This kind of antenna uses splash plate feed based on ring-focus antenna. The theory of the new splash plate feed design is presented and the relative equations are derived. The measured antenna parameters, VSWR, and patterns are highly consistent with the simulated results, which demonstrates the success of the design for such kind of antenna that can be effectively used in Ka-band applications.
