Abstract
A waveguide feeding array antenna is provided to be capable of separating and taking up each of the polarization components of the horizontal and vertical polarized waves received concurrently at an opening of each of a plurality of waveguides arranged to form a network, by means of a taking-up equipment disposed in the waveguide circuit. The both polarization components can be made thereby to be effectively separated from and composed with each other while realizing the simplification and economization of the waveguide network.
