We present an analysis of a slot cut in a broadwall of a rectangular waveguide, coupling into a semiinfinite rectangular waveguide capped by a conducting transverse plate containing the slot. Slots coupling into butt‐ended waveguides are employed in test fixtures in slot array applications. Pertinent integral equations for the slot‐aperture electric field are solved by the method of moments, and scattering characteristics of slot couplers for butt‐ended guides are deduced. Numerical results indicate limitations of these couplers for applications involving reduced‐height guides. © 1994 John Wiley & Sons, Inc.
