Measurement-Based Evaluation of Vertical Separation MIMO Antennas for Base Station

It is worth noting that the use of vertical separation antenna configuration provides an easy way to form large separation on a single pole. In this letter, the effect of vertical separation multiple-input-multiple-output (MIMO) antenna configurations for base station is investigated by field drive tests. The results show that vertical separation antenna configurations can meet the requirement of spatial multiplexing and provide good MIMO performance. Furthermore, measurements of MIMO antenna arrays were conducted to evaluate the performance of radiation patterns with interaction between antennas. The results show that vertical separation antenna configurations can reduce or avoid mutual coupling between antennas and improve the performance of antenna radiation patterns.
