The Effect of an External Electromagnetic Field on Orthogonal Coupled Microstrip Transmission Lines

Abstract

Abstract-The response of a two-layer structure of orthogonal coupled microstrip transmission lines illuminated by an external electromagnetic field has been studied. A simple model for the crosstalk region using lumped capacitance and inductance elements is used. The effect of the external EM field on the microstrip lines will be obtained using the method taking into account the EM field in order to reach transmission line equations along the lines. The model is finally validated using the full wave analysis simulator, HFSS. Voltage and current along the lines obtained by the present method are in good agreement with the results of the full wave analysis (HFSS). The proposed model has been used for voltage and current in terminal ports up to 10 GHz. This method can be developed simply for multilayer structures.

Electrostatics of crossed arrays of strips [Correspondence]

“…spurious capacitances between strips are of serious importance for PcBs of high-speed digital systems and microwave devices. The resulting signal cross-talk between strips is usually evaluated numerically [1]- [3]. The case of mechanically coupled piezoelectric resonators, sensor matrices, and actuators is similar.…”
