Abstract
PURPOSE:To form a small sized portable satellite communication equipment by forming the trunk cover by a transmission/reception antenna respectively, opening the cover at the communication so as to direct the antenna and a feed horn to a prescribed direction. CONSTITUTION:The RF equipment of a transmission RF equipment and the RF equipment of a reception earth station are both formed into a trunk accommodation type. Parabolic reflecting mirrors 11, 12 are placed to the part corresponding to the trunk cover and a power amplifier 7, a transmission frequency converter 9 or a low noise amplifier 8 and a reception frequency converter 10 are provided to the containing box. Then horns 21, 22 and polarized wave converters 41, 42 are removed from the trunk in the operation and placed on the upper face of the trunk in opposition to the reflecting mirror. Then the horns 21, 22, the transmission polarized wave converter 41 and the reception polarized wave receiver 42 are interconnected by a cable. Thus, small sized portable horn feeding system is formed.
