PURPOSE:To allow a reception section provided at the same outer face of a waveguide to receive both polarized wave signals by arranging longitudinally reflecting plates to another reception section for a polarized wave signal having differet phase and its rear directions. CONSTITUTION:A parallel component signal is reflected at the edge of a reflecting plate 12-2 tilted by 45 deg. to an H polraized wave signal passing through a reflecting plate 12-1 while its phase is inverted by 180 deg.. On the other hand, the vertical component signal is not reflected in the reflecting plate 12-2 but reflected in a short-circuit plate 9-2 arranged in front by lambdag/4 from the rear face of the reflecting plate 12-2 while the phase is inverted by 180 deg.. The reflection signal is led by 180 deg. being a phase corresponding to twice the length of the reflecting plate 12-2, i.e., a phase corresponding to lambdag/2 until the H polarized wave signal reaches the edge of the reflecting plate 12-2, resulting that the signal is reflected in a form of the vertica component signal having the phase as the original phase. The V polarized wave signal after the conversion is received efficiently from the upper face being the same plane as that of a waveguide 9-1 by using the reflecting plate 12-1 and a probe 11-2 being a component of a coaxial waveguide converting section 10-2. |
