Analysis and design of TE/11/-to-HE/11/ corrugated cylindrical waveguide mode converters
Abstract
A theoretical parametric study is given of a TE(11)-HE(11) mode converter consisting of a section of cylindrical corrugated waveguide with varying slot depth. The analysis makes use of modal field-matching techniques to determine the scatter matrix of the mode converter from which its propagation properties are deduced. It is shown that a mode converter consisting of only five slots achieves a return loss better than 30 dB over the band 2.7-3.8 ka (where a is the internal radius of the waveguide) with the HE(11) mode in the balanced condition at ka = 2.9. The predicted results are in very good agreement with experimental data.
