PURPOSE:To attain the suppression of the interference between different polarized wave signals in its own station without giving any distortion to a substantial transmission signal by using a signal from a bypass so as to cancel the quantity of interference from a polarizer. CONSTITUTION:A synthesis circuit 9 and a branch circuit 10 are inserted respectively on the way of a couple of transmission lines 3, 4 for different polarized wave signals led out of a polarizer 2. The length of a bypass 11 is selected so as to have a difference by lambda/2 (lambda is the wavelength of the signal center frequency) with respect to the length of the transmission line comprising branch circuit 10 signal transmission line 4 polarizer 2 signal transmission line 3 synthesis circuit 9. Thus, the interference from the polarizer 2 is eliminated nearly completely thereby reducing the mutual interference quantity in its own station between different polarized waves.
