摘要 提出一种应用于MIMO无线通信系统移动终端的腰带式可穿戴外置多天线。这一MIMO多天线系统利用合理的布局,可获取各种分集增益。天线单元采用开槽的电磁耦合微带贴片天线,减小了天线尺寸,也降低了人体吸收率。通过MI-MO系统试验平台的外场测试,得到了多天线系统的相关性系数矩阵以及误码率等重要的实验数据。测试结果表明:在保持总发射功率不变的情况下,相较于传统的单发单收天线,这一多天线系统可显著降低传输误码率,进而有效提高通信系统容量与质量。 This paper presents a type of wearable antennas integrated on a strap which adopted at mobile terminal in MIMO system. Through reasonable antenna distribution, a variety of diversity gains are achieved by using this MIMO antenna. The unit of the antennas is microstrip patch antenna, and it is fed by EM coupling for the need of the system＇s bandwidth. In order to reduce the size of the antenna, two rectangular slots are added on the patch. The SAR（Specific Absorbed Radiation） can be decreased using this antenna, too. Through the outfield experiment, the BER and the correlation matrix of the antennas can be obtained. These results show that the antenna system works well and meets all the design requirements.
