In this paper, the crosstalk and radiation of multiple-core cable is analyzed according as the multiconductor transmission line, two ports network and antenna theory . firstly the fundamental theories are presented 本文主要依據(jù)多導(dǎo)體傳輸線理論、二端口網(wǎng)絡(luò)理論和天線理論對(duì)多芯電纜的耦合泄漏和輻射發(fā)射進(jìn)行了較為詳細(xì)的分析討論。
Then multiconductor transmission line model is established . a spinning model is brought forward while analyzing the crosstalk of twisted-pair . it roundly shows the actual structure of twistedpair and greatly improves the calculating precision 在分析雙絞線耦合泄漏時(shí)提出了空間旋轉(zhuǎn)的模型,該模型較全面地反應(yīng)了雙絞線在空間360扭絞的真實(shí)結(jié)構(gòu),大大地提高了計(jì)算的精確度。
