Mobile satellite communications systems using 100-beam-class multibeam on-board antenna have been proposed and some of them are already in operation. Such systems can concentrate the resource, such as bandwidth, power, etc, on a specific beam. Therefore, these are effective for emergency operation under natural disaster. For such kind of the on-board antennas, size and power consumption are important to install the antenna in the satellite. In this paper,we studied a tradeoff on the on-board antenna from the view point of size and power consumption. For that purpose, the size is evaluated by the element number of the feed-array. The power consumption is evaluated by that of High Power Amplifiers (HPAs) connected with the elements, because the power consumption of HPAs dominates that of the satellite payload. |
