本文对一种高效的原型天线阵进行了深入的分析，主要目的是为MIMO基站天线阵和系统评估提供基准。给出了单单元、双极化天线和采用空气介质贴片单元以最小化损耗的四单元平面阵列的结果。测量的输入响应数据表明，谐振频率与FDTD仿真结果的一致性在1%以内。单元件是高度线性极化的，最大增益为10dB，估计效率为95%(所有测量误差已被系统识别)。这种2×2平面阵元的互耦小于−25dB，每个阵元的方向图相关性几乎为零，并且每个阵元的嵌入远场辐射方向图几乎相同，因此非常适合于多输入多输出系统评估。
This paper describes the thorough analysis of a highly-efficient prototype antenna array primarily aimed at providing a benchmark for MIMO base station antenna array and system evaluation. Results for a single element, dual-polarised antenna and a 4-element planar array employing air-dielectric patch elements to minimise losses are presented. Measured input response data show agreement in resonant frequency with FDTD simulations to within 1%. The single element is highly linearly polarised, has a maximum gain of 10dB and an estimated efficiency of 95% (all the errors in measurement having been identified systematically). The 2×2 planar array of elements has mutual coupling less than −25dB, almost zero pattern correlation and almost identical embedded far-field radiation patterns for each element, and thus ideal for MIMO system evaluation.
