Parametric analysis of the radiation characteristics of a multiple-folded phased array antenna

摘要

A high gain antenna with a large aperture is required on a satellite for satellite communications, remote sensing, microwave power transmission, or scientific exploration. An important problem is how to obtain a large aperture in an orbit while being folded small in a rocket in a launch stage. There have been proposed several schemes to fold and deploy large parabolas [1] [2]. The tensioned truss antenna was launched in orbit [3]. In order to achieve even smaller folded volume, however, parabola antennas have difficulties due to the necessity of three-dimensional structure and mechanical stiffness.
