Study on optimization of mechanical and electronic synthesis for the antenna structural system

Abstract

Integrated optimization design of mechanics and electronics for the high performance reflector antenna is considered in this paper and an efficient synthetic method is developed. A general mathematical expression of the phase centre for reflector antenna feeds is given. A very useful formula of a mathematical relationship between the electromagnetic field and the structural deformation of the antenna is then described, which provides a good complement for Rutz's formula. Moreover, the paper submits three typically mathematical models for synthetic optimization design of mechanics and electronics (SODME) for the antenna structural system, on which a good foundation is laid for the realization of SODME in practical engineering. As a demonstration, research work is applied to the design of an 8 m antenna used in a satellite-earth station and useful results have been achieved.
