摘要：
In December 2018, satellite broadcasting of ultra-high-definition television (UHDTV) will begin in Japan. For broadcasting UHDTV, BSAT-4a satellite was successfully launched. The satellite has not only 12-GHz-band right-and left-hand circular polarization transponders but also a 21-GHz-band experimental transponder. To receive services provided over these two frequency bands and with dual-polarization, we designed a dual-circularly polarized parabolic reflector antenna fed by 12-and 21-GHz-band microstrip antenna arrays with a multilayer structure. Finally, we confirmed through simulation that the designed antenna satisfies our requirements.
