摘要

本文介绍了5G多输入多输出(MIMO)天线的设计。该天线为双频天线，工作在28ghz和38ghz的毫米波频率。它也是双极化的，可以在垂直和水平极化之间切换。该子阵列由四个间隙耦合微带开槽双带贴片天线与公司微带馈电网络组成。该子阵列在28 GHz和38 GHz时的实现增益大于12 dBi，在28 GHz和38 GHz时的10 db带宽约为1 GHz。天线子阵列设置在八角形棱镜的两侧，以合成多波束辐射方向图，在棱镜的每侧分布12个子阵列。所提出的天线具有通过在放置在棱镜两侧的天线子阵列之间切换来将图案转向特定方向的能力。该天线实现了极化和模式分集，满足了5G系统在高增益、足够带宽、MIMO配置和固定波束切换能力方面的要求，是5G基站的良好候选者。

Design of Dual-band Dual-polarized MIMO Antenna for mm-wave 5G Base Stations with Octagonal Prism Structure

This paper presents design of 5G multiple input multiple output (MIMO) antenna for 5th generation (5G) base stations. The proposed antenna is dual band and it operates at millimeter-wave (mm-wave) frequencies 28 GHz and 38 GHz. It is also dual-polarized and it can switch between vertical and horizontal polarizations. The sub-array is formed of four gap-coupled microstrip slotted dual-band patch antennas with corporate microstrip feed network. The sub-array exhibits realized gain greater than 12 dBi at 28 GHz and 38 GHz and 10-dB bandwidth of around 1 GHz at 28 GHz and 38 GHz. The antenna sub-arrays are arranged on the sides of an octagonal prism to synthesize multi-beam radiation patterns with twelve sub-arrays distributed on each side of the prism. The proposed antenna has the capability of steering the pattern to particular directions by switching between antenna sub-arrays placed on either side of the prism. The proposed antenna is a good candidate for 5G base stations as it achieves polarization and pattern diversity and fulfills 5G system requirements in terms of high gain, adequate bandwidth, MIMO configuration and fixed beam-switching capability.
