论文摘要
在本文中，研究了多模式天线的相位中心的位移。为了计算每种模式的相位中心的位置，采用数学方法。使用从电磁场仿真数据获得的电气远场样品，确定相对于天线的物理中心，确定了每个模式的相对于天线的物理中心的移位位置的坐标。数值结果表明，天线原型的相位中心的依赖性是所考虑的观察角的函数。
In this paper, the displacement of the phase centers of multi-mode antennas is investigated. A mathematical approach is applied in order to calculate the positions of the phase center for each mode. Using electric far field samples obtained from electromagnetic field simulation data, the coordinates of the shifted positions of the phase center relative to the physical center of the antenna are determined for each mode. Numerical results show the dependency of the phase centers of an antenna prototype as a function of the considered angle of observation.
