Analysis of rectangular waveguide coupled on the effect of waveguide dimensions in common narrow wall

摘要

Waveguide slot couplers of present interest consist of longitudinal slot in the common narrow wall of two rectangular waveguides. The concept of self-reaction and discontinuity in model current are used for the analysis. The slots are designed in such a way that they are operated at resonance. It is an established fact that coupling depends on slot dimensions and its parameters along with frequency variations. But it also depends on the waveguide dimensions with which the coupler is fabricated. No data is available in literature on such dependence and effects. In view of this investigations are carried out to obtain such vital data. The effects of waveguide dimensions are consolidated in the present paper.
