TLDR
In this paper, the authors present closed-form expressions for the design of a quarter-wave transition-matching transformer, which takes the form of a notch or protrusion cut in the finline substrate at the waveguide-to-finline interface.Abstract:
This paper presents closed-form expressions for the design of a quarter-wave transition-matching transformer. This structure takes the form of a notch or protrusion cut in the finline substrate at the waveguide-to-finline interface. Measurements show a 5 db improvement in return loss over a full waveguide band due to such a transformer.read more

Modal-S-Matrix Design of Optimum Stepped Ridged and Finned Waveguide Transformers
Jens Bornemann,Fritz Arndt +1 more
TL;DR: In this article, the authors proposed a method of field expansion into eigenmodes, which includes higher order mode interaction between the step discontinuities, to achieve a minimum return loss of about 36 dB, or 34 dB for the whole Ku- or E-band, respectively.

Design of a new dielectric-slab phase shifter in a rectangular waveguide
TL;DR: In this paper, a phase shifter based on the insertion of a dielectric slab allowing the change of the propagation constant is presented. But the phase shifting is not considered in this paper.

Experimental studies of the peak power-handling capacity of finlines at centimeter and millimeter wavelengths
TL;DR: In this paper, experimental results confirm the validity of the theoretical model within a reasonable limit, when the uncertainties produced by the various parameters pertaining to the electric breakdown phenomenon are taken into account.
