Even-mode characteristics of the bilateral slotline

Transmission line data for the even-mode characteristics of a bilateral slotline (double-sided slotline) are presented. The slotline is analyzed by the spectral Galerkin method, and results are presented for the slot wavelength and characteristic impedance for substrates having epsilon /sub r/=2.22, 3.5, 6.0, 9.8, and 12.8. The results are presented for 0.01>
