Abstract

PURPOSE:To make it possible to transmit and receive arbitrarily polarized radio waves by providing a means which separates the horizontal polarized wave output and the vertical polarized wave output of an antenna from each other and a means which controls the phase and the synthesis of both separated outputs. CONSTITUTION:Circuits where switches 2 and 4 for 452 polarization and 902 phase shifters 3 and 5 are connected in parallel and the horizontal polarized wave and the vertical polarized wave are separated from each other is connected to antenna 1, and one of outputs of both circuits is inputted to forward/backward selector switch 7 through circular polarization/linear polarization selector switch 6, and the output is outputted as a circularly polarized wave output terminal 10 through directional coupler 9. This unit is so constituted that an arbitrary polarized wave may be outputted to output terminal 10 by operating horizontal/vertical switch 8 when switch 6 is connected to the lower side.
