摘要

以前曾报道过一种紧凑型MIMO接收机(R.R. Muller等人,2005),该接收机仅使用单个有源接收天线和多个无源元件来实现空间分集。无源元件用于构建合适的天线方向图,可以360度旋转以实现MIMO效果。本文讨论了可用于此目的的一些天线方向图。给出了一种具有1个主动偶极子和6个被动偶极子的天线的实例。选择有源偶极子与无源元件之间的距离为λ /8,这意味着天线系统的直径约为λ /4。此外,从不同频率的互信息角度考虑了该天线系统的宽带特性

Appropriate Antenna Patterns For A Compact MIMO Receiver
A compact MIMO receiver is reported previously (R.R. Muller et al., 2005) which uses only a single active receiving antenna and multiple passive elements to achieve spatial diversity. The passive elements are used to construct suitable antenna patterns which can be rotated 360 degrees around to achieve a MIMO effect. This paper discusses some antenna patterns which can be used for this purpose. An example of an antenna with one active dipole and 6 passive dipoles distributed on a circle around it is given. The distance between the active dipole and the passive elements is chosen to be lambda/8, which means that the antenna system will have a diameter of approximately lambda/4. Further the broadband properties of this antenna system is considered in terms of mutual information for different frequencies
