在本文中，我们提出了一些基本的调查，以显示一个共同的小终端上的天线的元素相关性和这些天线所激发的底盘上的特征模式之间的关系。结果表明，天线阵的特性受底盘的加权特征电流模式的影响很大。然而，对于给定频率，实际模式及其重量取决于底盘的尺寸和天线元件的位置。在两个天线系统的情况下，可以通过以两个天线都激励180°异相的相同模式的方式定位天线来最小化公共接地板对元件相关性的影响。
In this paper we present some basic investigations to show the relation between the element correlation of antennas on a common small terminal and the characteristic modes on the chassis excited by those antennas. The results show, that the characteristic of an antenna array is heavily affected by the weighted characteristic current modes of the chassis. The actual mode and its weight, however, depend on the dimensions of the chassis and the locations of the antenna elements for a given frequency. In case of a two antenna systems the effect of the common ground plate on the element correlation can be minimized by locating the antennas in such a way that both excite the same mode 180° out of phase.
