The E-Plane Taper Junction in Rectangular Waveguide

This paper compares formulas for reflection in rectangular waveguide from an E-plane junction with radial guide. There is a major discrepancy between results for the junction parameters from earlier results of the author and those in the Waveguide Handbook. The two sets of results are discussed; the Handbook result is apparently in error, but the formulas do not seem capable of reconciliation. Limitations and slight improvements on the author´s earlier result are given, together with supporting measurements taken at X band.
