Abstract

PURPOSE:To achieve samll size, light weight and economy, by commonly using transmission lines to give phase difference with two different frequencies. CONSTITUTION:To give a phase difference lambda/4 between microwaves f1 and f2 inputted to input terminals 16 and 17, they are distributed with equal amplitude at two T-branch circuits T-WG20 and T-WG21 provided on a waveguide WG22. One of the microwaves branched at the T-WG20 outputs a straight line polarized waves from an input hole 30 of a circular waveguide 27 via the WG22 at F1l1 in electric length and another microwave f1 outputs straight line polarized wave from an input hole 31 of the circular type waveguide 27. The circular polarized wave of the microwave f1 is generated in the waveguide 27 by setting the electric length of the WG22 to a prescribed value. Similarly, the microwave f2 can be transmitted as the circular polarized wave in the waveguide 27.
