Abstract

We developed low side lobe compact reflector antennas of aperture diameter of 60cm and 120cm. They are corresponding to 30 and 60 wavelength. These antennas are axial symmetry antennas using a backfire primary radiator. They are used in Ku-band mobile satellite communication. The requirements of antennas are low side lobes and low cross polarization. The antennas have satisfied ITU-R recommendation S.580-6. This paper introduces the structures and the radiation patterns of the antennas.
