In this paper we analyze the nonsymmetrically shielded suspended stripline (NSSS) by using the rectangular boundary division method. The characteristic impedance, wavelength reduction factor and attenuation constant of the NSSS are calculated, with special attention to the influence of the thickness of conducting strip. In the thin strip limit our analysis results agree well with those in the literature. When the strip conductor becomes thick enough, howeve, our numerical results show a considerable discrepancy of the propagation characteristics from the thin strip case. Some experimental results on the line capacitance are also presented for a comparison between theory and measurement.
