Abstract
Multiple-input-multiple-output (MIMO) antenna will play a key role in the development of fifth generation (5G) wireless mobile communication systems due to their performance-enhancement capability in multipath environment. Antenna radiation efficiency is an important parameter for MIMO antenna system. In this paper, we present a comparison of MIMO antenna efficiency measurements performed in Anechoic Chamber (AC) and Reverberation Chamber (RC) at the UK National Physical Laboratory. Two commercial available directional dual polarized full LTE band MIMO antennas were measured both in AC and RC between 1 GHz and 3 GHz.
