Optimal Design and Manufacture of a Composite Antenna using Gradient base Algorithm

Abstract
Recently, researches on lightweight antenna have been conducted for developing the low cost and high efficiency satellite antenna. A deployable solid antenna using CFRP is one of them. The CFRP has the advantage of low density and low thermal expansion coefficient. It is necessary to optimal design the antenna that can simultaneously consider the mechanical and electrical characteristics to design and manufacture the deployable solid antenna using CFRP. In this research, a SQP technique based on the gradient method is used among the optimum design techniques. The antenna reflector is designed and manufactured to minimize thermal deformation and to minimize antenna performance degradation is a space environment with large temperature variations Index Terms—Optimization, SQP, CFRP
