Element correlation of MIMO antennas on small terminals

This paper aims at investigating some significant integration aspects involved in daily practical mobile terminal design and their impact on the correlation coefficient of multiple antenna elements. While the antenna elements itself are kept as simple as possible the influence of its location on the terminal platform is investigated systematically. The investigations show, that the influence of the integration is significant on the one hand. On the other hand the general physical behaviour can be easily estimated and can also be used to find simple design rules for closely spaced de-correlated antennas on small terminals.
