Proposal of the performance evaluation method for a MIMO antenna

This paper has proposed the evaluation method of the MIMO antenna performance including frequency characteristics. Since the performance of the MIMO antenna depends on both radiation efficiency and correlation coefficient, the task for evaluating the antenna, especially including frequency characteristic is heavy and time consuming. The effective radiation efficiencies based on the radiated power and the MIMO channel capacity have been proposed and fundamental numerical data were presented. The relation between the effective radiation efficiencies and the MIMO channel capacity will be investigated and the applicable condition should be clarified in detail.
