Simulation of Crosstalk on Printed Circuit Boards by FDTD, FEM, and a Circuit Model

The aim of this work is to study crosstalk between microstrips on printed circuit boards with the finite element method, the finite difference time domain method, and a circuit model up to several gigahertz. One simple benchmark problem for near end cross talk and one for far end crosstalk have been manufactured and analyzed. Measured scattering parameters are compared with simulated ones obtained by the different methods. Numerical aspects are presented and discussed.
