Abstract (in Japanese) (See Japanese page) 
(in English) In order to overcome the large rain attenuation in the 21GHz band, a reconfigurable antenna with an array-fed reflector is effective for the 21GHz-band satellite system. We designed and manufactured an experimental model of an array-fed imaging reflector antenna for the 21GHz-band broadcasting satellite system. We verified the characteristics by measurement. We describe the configuration of the manufactured antenna and the radiation pattern of the imaging reflector calculated by using the measured radiation pattern of the feed array. A 7dB boosted beam has been successfully obtained.
