A rectangular wave-guide 1 is coupled to an adjacent guide, not shown, by a coupling flange 2 in which, in order to prevent leakage, there are cut channels 3 running the whole width of the larger dimension of the guide, and slots 4. The slots 4 are a quarter-wavelength deep and are a quarter-wavelength from the broad side of the guide. To simplify manufacture, the slots 4 have the form in plan shown in Fig. 3, that is a segment of a circle, the centre being just outside the flange. This enables the slot to be cut by a simple milling cutter. The effective depth of the slot may be increased by a filling of polystyrene. Fig. 4 shows a recess 8 of the same shape as slot 4 used as an impedance transformer between a normal sized guide (not shown) and a very narrow guide 5 adapted for feeding a crysal detector 6 as described in Specification 650,614.
