This paper presents a hybrid mode analysis of wide slot lines on low-permittivity substrate. The dispersion characteristic and characteristic impedance of the structures are obtained by applying the Fourier transform domain technique and evaluating the resulting expressions numerically using the method of moments. The power-voltage definition of characteristic impedance is adopted in the deriva- tion of characteristic impedance. The results for the characteristic impedance of wide slot lines on low- permittivity substrate are presented. The results for the characteristic impedance of narrow slot lines on high-permittivity substrate by using the present method are compared with those available in the litera- ture showing a good agreement. 窄槽线 宽槽线 特征阻抗 narrow slot line wide slot line characteristic impedance TN454 1993-01-01 2021-04-01 1
