On the Plurality of Solutions in Synthesizing Asymmetric Multi-Element Coupled-Transmission-Line Directional Couplers SHIBATA, Koji 32439 SHINADA, Yuji 32440 MATSUMOTO, Akio 32441 application/pdf It is the purpose of this paper to point out the general plurality of solutions in synthesizing asymmetric multi-element coupled-transmission-line directional coupler. In this synthesis　method，the coupling coefficient of each element is determined on the basis of the analysis of F matrix by using the power division ratio between the two output ports. Applying this synthesis procedure to the asymmetric multi element coupled-transmission-line directional coupler(n≧4)，we have found the solution satisfying the given transmission characteristic has plurality，and the coupling coefficients calculated by this synthesis are tabulated for 3,4,5 and 6 elements coupler. departmental bulletin paper 北見工業大学 1976-06 application/pdf 北見工業大学研究報告 2 7 351 391 https://kitami-it.repo.nii.ac.jp/record/6397/files/7-2-8.pdf https://kitami-it.repo.nii.ac.jp/records/6397 eng
