Abstract
692,336. Wave-guides. SPERRY CORPORATION. Oct. 23, 1951 [Oct. 24, 1950], No. 24715/51. Class 40 (viii). A rectangular wave-guide 10 and a circular wave-guide 12 are coupled by two means, so arranged that, when a TE10 wave is transmitted along guide 10, the first coupling means introduces into guide 12 energy, the electric vector of which is parallel to that of the energy in guide 10, and the second coupling means introduces into guide 12 energy which is in phase quadrature with, and has its electric vector at right-angles to the energy introduced by the first coupling means. A circularlypolarized TE 11 wave is thus produced in the circular guide. In the arrangement shown, the first coupling means consists of a coaxial 15, or a twin wire line with dipoles 20 and 25 or coupling loops at each end. By placing these coupling means at right angles, this coupling device transmits energy to guide 12 which has its electric vector at right-angles to that in guide 10. Further, owing to the different wave velocity in the coaxial line, this energy differs in phase from that passing from guide 10 to 12 by a drect connection, as shown, and having its electric vector always parallel to that of the energy in guide 10. In order to match the coupling better, an intermediate section 40 of rectangular guide may be provided, and this may be joined to guide 10 by a matching portion 50. The parts 40 and 50 may be replaced by a single flared part having a rectangular aperture at one end and a circular at the other.
