Characteristic Impedances of Generalized Rectangular Transmission Lines

The impedance of the generalized strip transmission line is computed by variational methods. The use of an upper bound and lower bound approximation yields an average impedance as well as a known maximum error. The one-dielectric microstrip line is treated as a limiting case. Losses are considered. Results include those problems which have been solved elsewhere by conformal mapping techniques as special cases.
