Abstract

Abstract:

A modeling and simulation analysis method based on model simplification is proposed to solve the problem of electromagnetic coupling interference in the microstrip line of PCB, which is connected to each module in the small interior of the portable chassis and is responsible for the function of information energy transmission and exchange. In this paper, the chassis model is modeled and simplified according to the micro-winding theory. Combined with the electromagnetic model modeling of the PCB inside the chassis and the microstrip line on it, and the adding of corresponding clock signal excitation and load on the microstrip line,the simulation analysis of the coupling characteristics of the microstrip line without PCB is realized. The results show that when the relative spatial position of the interference PCB is perpendicular or parallel, the coupling voltage peaks of the microstrip line are 1.3 mv and 0.5 mv, respectively. The overall change trend is related to the rising and falling edge of clock signal, and the coupling voltage on the vertical and parallel PCB is positively and negatively correlated, respectively.

Key words: microstrip line, electromagnetic coupling characteristics, model simplification, time-domain response characteristics, the Fourier transform, clock signal, finite difference time domain
