【 摘 要 】

References(4)Cited-By(5)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.
