This paper mainly studies the coupling error caused by induction voltage phase difference , and fluctuation of directional sensitivity caused by changes in near - field difference slope . the trend of system sum and difference phase difference , directional sensitivity and cross - coupling with change in distance is compared and discussed when the antenna is in the near - field and at a certain elevation 本文着重研究了因近场感应电压相位差引起的耦合误差,以及近场天线差斜率变化引起的定向灵敏度的变化;讨论了天线在近场并有一定仰角的条件下,随着距离的变化,系统和、差相位差、定向灵敏度与交叉耦合的变化趋势。
