Innovative Antenna Solutions for Satellite Telecommunications

Abstract

The paper deals with high performance scanning antennas for satellite applications. By referring to array antennas, we propose an optimal synthesis approach able to determine the excitations of the array elements that can be reconfigured with tunable metamaterials for the realization of beam scanning. The achieved results are satisfactory and show improvements with respect to benchmark state of the art. Then, slot array antennas have been identified as possible realization technology in conjunction with electrically tunable nanomaterials. A preliminary characterization of the loaded-slot in terms of radiated power is presented.
