摘要

本文提出了一种四元MIMO天线系统。提出的设计方案由一个两单元印刷f形平面单极天线(PMA) MIMO天线与一个两单元槽天线集成组成。这些槽出现在地平面上，作为隔离器和散热器。槽天线由印制在槽背面的50Ω微带线馈电。f形天线谐振于WLAN的中心频率2.495 GHz，而槽形天线谐振于UMTS频段的中心频率2.175 GHz。MIMO天线的整体尺寸为50 × 110 × 1.56 mm3。Ant-1和Ant-2与Ant-3和Ant-4之间的最小隔离度分别为- 15dB和- 14dB。地面的插槽不仅提高了WLAN的带宽，而且在2.175 GHz处产生了额外的共振，进一步降低了Ant-1和Ant-2之间的相互耦合。此外，利用数值模拟软件计算了所有分集和辐射参数，发现它们适合MIMO应用。

4-Elements MIMO System Integrated with Planar Monopole and Slot Antenna for Wireless Applications

In this paper, a four element MIMO antenna system is presented. The proposed design consists of a two element printed F-shaped Planar Monopole Antenna (PMA) MIMO antenna integrated with a two elements slot antenna. These slots are presented on ground plane and acts as an isolator as well as radiator. The slot antenna fed by 50Ω microstrip line which is printed on back side of the slots. The F-shaped antenna is resonating at centre frequency 2.495 GHz of WLAN whereas slot antenna operates at centre frequency 2.175 GHz of UMTS band. The overall size of proposed MIMO antenna is 50 × 110 × 1.56 mm3. The minimum isolation between Ant-1 & Ant-2 and Ant-3 & Ant-4 are −15dB and −14dB, respectively. The slots on the ground not only improve the bandwidth at WLAN but also creating additional resonance at 2.175 GHz that further reduces the mutual coupling between Ant-1 and Ant-2. Moreover, all the diversity and radiation parameters are calculated using numerical simulation software and found suitable for MIMO application.
