The accuracy of microstrip radial stub computer‐aided design (CAD) models is investigated both experimentally and against electromagnetic simulations. A dual‐resonator technique is used to eliminate confounding variables and to obtain accurate experimental data. This technique is extended beyond the earlier perturbation analysis applied to discontinuities to enable checking models that have significant electrical length. Model phase errors in excess of 16° have been found for the microstrip radial stub. © 2000 John Wiley & Sons, Inc. Int J RF and Microwave CAE 10: 95–107, 2000
