ABSTRACT:
An antenna system in which main and subreflectors are arranged in such a manner to suppress the generation of a cross-polarized component due to the antisymmetry of the reflectors. Thereby, the antenna system can provide a preferable cross-polarization characteristics even in the working frequency bands.
