A unified dielectric loss model based upon the single-layer reduction (SLR) formulation is presented for the determination of dielectric loss of a multilayer lossy microstrip line with and without the top shield. The model hias accuracy within 0.05 dB/cm or 3% against the field-theoretic results from several sources. The computational efficiency of this model does not depend on the number of dielectric layers, and the model is valid up to the millimeter-wave range.
