摘要: An approximate analytical model for the CPW (coplanar waveguide) step discontinuity is presented which includes a lumped shunt capacitance as dominant effect. Good agreement obtained with data from extensive 3-D field simulations, and verified by limited number of measurements on alumina. The magnitude found to be smaller than indicated in previous work, but it nevertheless same order microstrip comparable situation. These effects need taken into account any serious design, presented, when incorporated CAD (computer-aided design) circuit analysis programs, will allow rapid evaluation performance. >
