An Analysis of Miniaturization of 5G Massive MIMO Base Station Antenna

Abstract

This paper reviews current works and efforts on the miniaturization of the 5G Massive MIMO base station antenna design. This paper first introduces the development of the Massive MIMO, with a proper mathematical illustration. Then, some conventional parameters are introduced to measure the performance of the antenna, with a connection to the miniaturization of the antenna. Specifically, two coefficients: the gain-to-volume ratio and isolation-to-volume ratio are constructed to measure the efforts in miniaturization. Tables that collect works in the literature are presented, with detailed comparisons among working situations. Then a general conclusion and future path of miniaturization are indicated. At last, the paper introduced the challenge and future of the miniaturization of the 5G Massive MIMO base station antenna.
