Computer-Aided Analysis of Stripline Circuits Including Discontinuity Reactance Effects

Abstract

For an accurate design of the strip line circuits, it is necessary to take the effects of parasitic discontinuity reactances into account. A computer-aided analysis technique developed forth is purpose is described in this paper. This involves characterization of each discontinuity in terms of s-parameters and incorporating these for calculation of overall s-parameters. Examples of various circuits are presented for illustrating the role of discontinuity reactances in stripline circuits. For a two-stub band-pass filter, the midband VSWR increases from unity to 1.09 and the centre frequency shifts from 3.0 to 2.7 GHz.
