Abstract in Undetermined
This study investigates the impact of user on the multiplexing efficiency of a pentaband two-element MIMO terminal antenna. At the 750MHz band, the results show that the antenna total efficiency decreases by 4 dB in the presence of the user hand. However, this negative effect is partly compensated by the de-correlation effect of the hand. As a result, the multiplexing efficiency of the antenna degrades by only 2.4 dB in the hand scenario, as compared to the free space scenario. Throughout the study, we show that the impact of user hand and head on the efficiency and correlation performance can be conveniently quantified using the multiplexing efficiency metric.
