This study estimates the accuracy of HFSS and Sonnet and other models against the experimental results from three sources. A closed‐form model for experiment based stopping distance is developed to calculate accurately conductor loss of CPW. The present improved Holloway and Kuester (IHK) model has an average accuracy of 3.7% against the experimental results from different sources in the frequency range 1–120 GHz with conductor thickness of 0.25–1.58 μm. The original Holloway and Kuester model has an average accuracy of 13.7% and model of Ponchak et al. 17.1 % against same set of experimental results. HFSS and Sonnet have average accuracy of 7.86% and 10.33% against same set of experimental data. The accuracy of IHK model is also examined against HFSS and Sonnet for the conductor thickness up to 9 μm and substrate relative permittivity in the range of 3.8–20. © 2009 Wiley Periodicals, Inc.
