Abstract

1376186 Waveguides LICENTIA-PATENTVERWALTUNGS-GmbH 9 Nov 1971 [11 Nov 1970] 51939/71 Heading H1W A waveguide device for producing a wave having rotating polarization from two orthogonal linearly polarized waves comprises wave coupling means disposed in two opposite inner corners of a waveguide capable of propagating the orthogonal waves. The coupling means can consist of pins projecting inwards from the corners, Fig. 2a, or quarter wavelength resonators at the corners, Fig. 2b (not shown). Alternatively, shutters of various shapes may be arranged in the corners, Fig. 3a, at quarter wavelength intervals. Alternatively, continuous projections may be provided, Fig. 4c (not shown). In another form, Fig. 5a, a plate extends along the diagonal of a square waveguide with the end of the plate having a V-shaped portion cut away. In Figs. 6a, 6b a similar plate consists of dielectric material with copper coatings.
