A Ku Band Small Reflector Antenna Using Backfire Primary Radiator for Satellite Communication System on Board Vessel

摘要

Recently, the demand for mobile broadband communications on aircrafts and ships has increased. There are a lot of worldwide demands for high-speed data communications in sea area. Introduction of the earth stations on board vessels (ESVs) system using the Ku band satellite communications systems has been started [1-3]. The authors propose an antenna for the system. It is necessary to conform to international and regional standards and regulations all around the world. For this purpose, antenna needs to be designed to achieve low side lobe with keeping high antenna efficiency. In this paper, we report the design of the small reflector antenna for the Ku band satellite communications system on board vessel.
