We propose an aperture coupling E-bend with step structure as a robust post-wall waveguide interface to an external standard waveguide in which the posts are separated from the aperture. A 61.25 GHz model transformer gives 11.4% bandwidth for the reflection below -25 dB by using a 1.2 mm-height dielectric substrate. We have compared the mechanical tolerances of both the conventional straight structure and the proposed step structure. The step structure is more robust against mechanical errors than the conventional one. Another advantage is that the accuracy of the analysis model for the post-wall to metal-wall replacement is enhanced for the step structure.
