摘要
为分析不同入射方式下的电磁波与微带线的耦合特性问题,将PCB板上微带线等效为有耗传输线模型,对辐照平面波进行矢量分析并求解等效激励源,利用BLT方程计算不同入射方式下的电磁波与微带线的耦合终端响应,针对仿真结果开展效应实验验证,仿真与实验结果吻合较好。研究表明,BLT方程可有效地解决电磁波与微带线的耦合问题,当电场平行于微带线或垂直于PCB平面入射时,可产生较强的耦合,且平行入射情况比垂直PCB入射情况在微带线终端激励起的峰值电压大一倍;幅度为1v/m的电场在微带线上激励的峰值电压可达到mV量级。
In order to analyze coupling characteristics between electromagnetic waves and the micros- trip lines under different incident modes, the microstrip line on ghe printed board （PCB） is converted equivalently to a lossy transmission line, and the plane wave vector is analyzed and the equivalent ex- citation source is solved, and the BLT equation is used to calculate the coupling terminal response between the electromagnetic wave and the microstrip line under different incident modes,the experi- mental verification is made according to simulation results, and both results are consistent. Studies have shown that,the BLT equation can effectively solve the coupling problem between electromagnet- ic waves and microstrip lines,and when the electric field is parallel to the mlcrostrip line or perpen- dicular to PCB,strong coupling can be produced,the peak voltage in the microstrip line terminal ex- cited by the parallel incident is twice that excited by the vertical incidence, each by the parallet inci- dent is twice that excited by the vertical incidence,each amplitude of the electric field excited in the microstrip line can reach the order of mV.
