6-4 The rain attenuation compensable advanced broadcasting satellite system (2) : a study of aperture field patterns of the onboard antenna

Abstract

This paper describes aperture field patterns in the rain attenuation compensable advanced broadcasting satellite system with an on-board large-scale phased-array anntena. We assumed a restriction curve of PFD(power flux density) outside of the service aria and some aperture field patterns which follows typical window functions. The allowable maximum PFD curve in the restriction was calculated
