ABSTRACT:
A circularly polarized wave-linearly polarized wave transducer using a waveguide characterized by expanding the inner wall of the section vertical to the tube axis of the waveguide in a taper form having a gradient in the axial direction of the tube. The taper gradient in the axial direction of the tube is different at plural parts in the circumferential direction of the inner wall, thereby producing a difference in the propagation constant of two modes orthogonal at a microwave frequency. The taper gradient and overall length of the waveguide are determined so that the phase difference of the two modes is .pi./4 at each end of the waveguide. The circularly polarized wave-linearly polarized wave transducer can be realized in a simple construction in which the core of a die in the die-casting process can be drawn out in only one direction.
