Abstract

A general analysis of a coaxial-line/radial-line region junction is presented for the case in which the center conductor is sheathed in a dielectric and extends the full width between two parallel metal plates. Expressions for the current distribution and the admittance of the junction are presented. Two example environments are considered, a rectangular waveguide and a base entrant cylindrical cavity, although the technique can be used for other environments. Comparison of theoretical and experimental results for these two cases shows the theory to be very accurate
