Electromagnetic coupling and radiation loss considerations in microstrip (M)MIC design

The high-frequency characterization of microstrip meander lines, junctions, and stubs is performed by the application of the method of moments to the electric field integral equation. Electromagnetic coupling, radiation, and substrate effects are inherently included with the use of the space-domain Greens function. Conductor loss is included by replacing the conductive strips with appropriate surface impedance boundaries. This results in an analysis of irregular microstrip discontinuities which accounts for both resistive and radiation losses.>
