摘要

本文提出了一种适用于5G NR手机应用的4×4 MIMO天线。设计了一种环形天线、边缘摄动和非对称共面波导馈电结构的单极天线接头，工作在5G NR FR1 (3300MHz-3600MHz和4800MHz-5000MHz)频段。制作了长10.2 mm、宽2.8 mm的天线样机并进行了实验研究。利用极化分集对四根天线进行布置。实验结果表明，天线间的隔离度(S21)大于20dB，包络相关系数(ECC)小于0.02。在5G NR FR1频段输入功率为23dBm时，比吸收率(SAR)满足FCC规定的1.6 mW/g的SAR限值。

4×4 MIMO antenna design for 5G NR FR1 mobile handset applications

A 4×4 MIMO antenna for 5G NR mobile handsets application is proposed in this article. A monopole antenna joints with loop antenna, edge perturbation and asymmetric co-planar waveguide (ACPW) feeding structure is designed to be operated in 5G NR FR1 (3300MHz-3600MHz and 4800MHz-5000MHz) bands. A prototype of the proposed antenna with 10.2 mm in length and 2.8 mm in width is fabricated and investigated experimentally. The polarization diversity is used to arrange the four antennas setup. The experimental results indicate that the isolation (S21) between the antennas is more than 20dB, and the envelope correlation coefficient (ECC) is less than 0.02. The specific absorption rate (SAR) for an input power of 23dBm in 5G NR FR1 band meet the SAR limit of 1.6 mW/g of FCC regulatory limit.
