Abstract (in Japanese) (See Japanese page) 
(in English) We developed off-set Cassegrain antenna optical system and 8 GHz band receiver for the ASTRO-G/VSOP-2 satellite. That is second generation satellite for the Space VLBI project, which is combing radio telescopes on the earth and the satellite. There are 43,22,8GHz band feed horns at Cassegrain focus. Feed horn of this satellite must have low cross polarization characteristic and small size. Multimode horn satisfies this conditions and have advantage in fabrication, which is short axial length and have simple wall. We introduce the Cassegrain antenna optical system with multimode horn and the 8 GHz band receiver.
