Abstract(in English) In case Tri-Reflector type offset antennas eliminating cross-polarized commponent based on geometrical optics are used in lower frequency bands, cross-polarized components due to the unsymmetry of reflectors remain because field distributions differ from those calculated based on geometrical optics. In this paper, the condition of no cross-polarized component of a Tri-Reflector offset antenna taking account of the change of field distributions due to frequency is derived based on beam mode analysis and is found to be a geometrical relation independennt of frequency. According to the result, possible configurations of reflector systems are shown and a design method of a compact antenna is presented.
