Abstract

PURPOSE:To make a transmitting wave and a receiving wave branch in a state that their polarized relation in the common transmission line has been kept, by constituting 2 orthogonal polarizations of a waveguide of transmittable dimensions, and connecting an electric power distribution having a metallic plate in the center, to a transmitting and receiving wave branching filter. CONSTITUTION:Each wave whose electric power has been divided by an electric power distribution 1 is transmitted and received, and is made to branch independently, and in this case, the wave is made to branch, keeping its phase relation as shown in the figure (c) and the figure (c'), by setting the respective upper and lower branching filters of a transmitting and receiving wave branching filter 4, to the same dimensions. Accordingly, when these 2 upper and lower waves are synthetizes by an electric power distributor 2 and 3, receiving waves of V and H and transmitting waves of V and H are made to branch to a terminal 21 and a terminal 31, respectively, keeping their polarized relation in the common transmission line in accordance with an input terminal 11.
