对MIMO应用中的调制散射阵列天线进行了实验研究。MSAA具有多天线结构，但它仅由一个普通天线单元和多个调制散射单元（MSE）组成。在2 × 2 MIMO系统中，当使用2单元MSAA作为MIMO天线时，在室内环境中测量指示MIMO性能的误差向量幅度（EVM）。结果表明，该方法可以建立2流数据链路。然而，2个流的EVM是相当不同的，并且由于MSE的增益降级而观察到平均7dB的差异，这指示MSAA可以用于其中简化MIMO天线系统的配置被高度优先考虑的MIMO应用中。
Modulated scattering array antenna (MSAA) for MIMO applications is experimentally studied. The MSAA has a multi-antenna structure, but it is composed of only one normal antenna element together with several modulated scattering elements (MSE). The Error Vector Magnitude (EVM) which indicates the MIMO performance is measured in an indoor environment when a 2-element MSAA is used as the MIMO antenna in a 2 × 2 MIMO system. It is demonstrated that 2-stream data link can be established. However, the EVMs of the 2 streams are quite different and an averaged 7dB difference is observed due to the gain degradation of the MSE, indicating the MSAA can be used in the MIMO applications where simplifying the configuration of MIMO antenna system is taken high priority.
