<p>A right-angle junction for rectangular waveguides, obtained by the 90 DEG coupling of two rectilinear rectangular waveguides of equal cross-sectional dimensions, which comprises two steps arranged symmetrically with respect to the coupling plane between two waveguides, with two dimensions equal to the dimensions of the guides and suitable thickness, and further possible symmetrical pairs of steps of length equal to about a guide quarter-wave at the centre frequency.</p> |
