Abstract

This paper describes the concept and the development of key components of a novel multiple-beam antenna for satellite applications. The antenna is designed to be used in a transparent high-rate data relay system that links several LEO satellites to a single ground station via a GEO satellite. The proposed antenna is based on the concept of array-fed reflector. The antenna can track LEO satellites by switching between different subarrays of a bigger multifeed array using a reconfigurable switch matrix based on micro-electromechanical system (MEMS) switches. The radiation characteristic of the antenna is further improved by combining digital beamforming with the beam switching. To validate the proposed antenna concept and show its suitability for space applications a demonstrator has been built. Measurements of the antenna key components of the antenna and the demonstration system are given.
