A study of Low Sidelobe Technology of Reflector Antenna and the Experimental Result of Decreasing its Sidelobe Level

For realization of STICS, a large satellite antenna is necessary. We have been studying the satellite antenna with approximately 30 m aperture size. For keeping the performance of beam shape, beam direction and sidelobe level, radiation pattern correction will be needed, because thermal distortion o...

Summary:For realization of STICS, a large satellite antenna is necessary. We have been studying the satellite antenna with approximately 30 m aperture size. For keeping the performance of beam shape, beam direction and sidelobe level, radiation pattern correction will be needed, because thermal distortion of reflector will be caused. In this section, radiation pattern correction experiment results are described, using developed digital beam forming network (DBF/channelizer) for studying ability of pattern correction of this DBF antenna.
