一种估算微带传输线辐射敏感性的解析电路模型
Analytic circuit model for radiated susceptibility estimation of the microstrip transmission line
摘要
Abstract
According to transmission line theory and electromagnetic theory,a time-domain analytic circuit model for radiated susceptibility estimation of a microstrip transmission line is proposed.In order to obtain the susceptibility threshold of a microstrip line under external electromagnetic interference quickly,a transverse electromagnetic cell (due to IEC standard 62132-2) is adopted as the test environment.A transmission line pulse is chosen as the external electromagnetic interference,since its steep edges can directly demonstrate radiated susceptibility of a microstrip line.This is an application case to identify the availability of the model.Specific parameters of the analytic circuit model are derived and comparisons of calculated and measured results of transmission line pulse responses for the matched microstrip line confirm the accuracy of the model.Furthermore,transmission line pulse responses of a microstrip transmission line with arbitrary loads and contributions of electric and magnetic field couplings are calculated.The effect of terminal load on the response of a microstrip transmission line is obtained,which can be helpful for load-selection to improve radiated susceptibility estimation of a microstrip transmission line.关键词
