Abstract
Power Satellite System needs a huge on-board antenna called a spacetenna. This antenna may be realized by a phased array antenna (PAA) which adopts elements of a half-wavelength in scale. In this case, the number of elements is quite large so that the simplification of feeding system is inevitable. This paper deals with a large-scale phased array antenna that is divided into sub-arrays, and equipped with a phase shifter to each sib-array. The effectiveness of the phase shifter reduction and the radiation characteristics in beam scanning are clarified.
