| Abstract(in English) | 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 number of elements are important to install the antenna in the satellite. If an element spacing and element size are set up appropriately, the number of elements can be reduced. In this paper, the optimal size of feed array elements in order to obtain required gain and number-of-elements redution was examined. |
