In this article, new and accurate synthesis formulas to compute the physical dimensions of open supported coplanar waveguides (OS‐CPWs) are presented. The synthesis formulas are obtained with the use of differential evolution (DE) and particle swarm optimization (PSO) algorithms. They are useful for the computer‐aided design of OS‐CPWs. The average percentage errors of the synthesis formulas obtained by using DE and PSO algorithms are computed to be 1.26% and 1.67%, respectively, for 4560 OS‐CPW samples having different electrical parameters and physical dimensions, as compared with the results of quasi‐static analysis. © 2009 Wiley Periodicals, Inc.
