Abstract A 4-port antenna is designed for evaluating the performance of an MIMO system in indoor environment. Diversity gain, correlation coefficient and channel capacity are calculated and discussed in this paper. The selection diversity becomes more unapparent when using more antennas in MIMO system. Correlation in both rich scattering and high K-factor environment are found below 0.2 and 0.5 respectively. Channel capacity is 82% of the ideal case with uncorrelated channel. The above-mentioned results suggest the effectiveness of the proposed antenna.
