A bended and straight coplanar waveguides are modeled by using HFSS 3D electromagnetic software. The behavior of bend CPW is described by matrix calculations in order to show the effect of the parasitic even mode on the propagation of a signal. A comparison is done in this article with several works done before to show that there is a significant error when using bended CPW standard instead of straight ones in calibration.
