4G天线电磁波辐射的笔直极化

发布日期:2015-05-13 00:00 来源:http://hbkfit.com 点击:

  振幅比和相位差均为恣意值时,电场矢量端点的运动轨道为一个椭圆,此刻波为椭圆极化波。线极化若以入射面为参阅可分为平行极化和笔直极化。入射面为由入射线、反射线与法线构成的平面。将电场与入射面平行的波称为平行极化波。电场与入射面笔直的波称为笔直极化波。在4G天线电磁波辐射工程中,通常取地上为参阅,将电场矢量与入射平面平行的极化(在于大地笔直的平面内)称为笔直极化;电场与与入射平面笔直(电场矢量平行于大地)的极化称为水平极化,这儿设地上为反射面,入射面是于大地笔直的平面。请注意两者极化界说的不一样,4G天线电磁波辐射中的水平极化和笔直极化通常是指后者。
