本文研究了实际移动的终端中满足波束控制、分集和多输入多输出（MIMO）传输要求的基本MIMO天线阵列布置。我们特别注意元素间距低于0.5 /spl lambda/的范围。使用安装在移动的终端上的大于0.2 /spl λ/的元件间距，通过卡型和膝上型PC型终端模拟，与单天线配置相比，在两元件配置和四元件配置中分别产生大约2.5 dB和5.0 dB的功率。此外，与单天线配置相比，两元件和四元件配置产生小于0.7的相关系数，并且分别实现1.6倍和3.2倍的MIMO容量。从综合的角度来看，安装在实际的移动的终端上的具有大于0.2 /spl λ/的元件间隔的多个MIMO天线可以根据具有期望的分集增益和可接受的MIMO信道容量的阵列大小以高增益操作。
This work investigates the fundamental monopole antenna array arrangement for actual mobile terminals that satisfies the requirements for beam-steering, diversity and multiple-input-multiple-output (MIMO) transmission. We take particular note of the range below 0.5 /spl lambda/ for the element spacing. Using an element spacing of greater than 0.2 /spl lambda/, mounted on the mobile terminals, simulated by card-type and laptop PC type terminals, resulted in approximately 2.5 dB and 5.0 dB more power in two- and four-element configurations, respectively, compared to the single-antenna configuration. Furthermore, the two- and four-element configurations yield a correlation coefficient of less than 0.7, and achieve 1.6 and 3.2 fold higher MIMO capacity, respectively, compared to the single-antenna configuration. From a comprehensive perspective, multiple monopole antennas mounted on an actual mobile terminal with an element spacing of greater than 0.2 /spl lambda/ can operate at high gain according to the array size with the desired diversity gains and acceptable MIMO channel capacity.
