Abstract

PURPOSE:To obtain right and left circular polarized wave reception output easily, by providing two orthogonal output probes on a circular waveguide and applying the output obtained at this output probe to a directional coupler. CONSTITUTION:An output received on a reception antenna 18 is given to a circular waveguide 15 to obtain a vertical component SV for an output probe 16 and a horizontal component SH for an output probe 17, which are applied to a directional coupler (3 dB coupler) 19. In the coupler 19, a signal applied to one or other input terminal is summed with a signal of other or one input terminal with phase shift by pi/2 to obtain outputs as one and other outputs SA and SB. Thus, a reception output is obtained for the output SA only to a right circular polarized wave of transmitted electromagnetic waves and the reception output is obtained only for the output SB to the left polarized wave. Then, the outputs SA and SB thus obtained are applied to SHF-UHF converters 22, 23 respectively through amplifiers 20, 21, and the UHF output signals are obtained at output terminals 24, 25.
