| Abstract(in English) | We study on the broadcasting satellite systems composed of onboard array-fed reflector to compensate for rain attenuation in 21GHz band. In this system, the array feed consists of more than 100 radiation elements which are closely located each other, therefore it is necessary to consider the effect of mutual coupling on the radiation pattern. We measured and calculated the radiation pattern of onboard array-fed reflector which has 20 radiation elements and a reflector (aperture diameter: 1.3m) for evaluating the accuracy of calculation. Moreover, we evaluated the effect of mutual coupling on the radiation pattern of the onboard large-scale array-fed reflector which has 144 radiation elements and a reflector (aperture diameter: 5m). |
