摘要

在总尺寸为118mm×86mm×1.67mm的RO3035上设计了WiMAX (3.30-3.70GHz)和卫星频段(6.99-8.09GHz)双陷波响应的四元超宽带(2-20GHz) MIMO天线。采用独特的去耦结构，提高了两个天线单元之间的隔离度(≤20dB)。研究了MIMO天线的基本特性，如带宽比(10:1)、隔离度(>18dB)、增益(4.14dB)、包络相关系数(<0.0065)、总主动反射系数(< 0dB)、信道容量损耗(<0.25bps/Hz)和辐射方向图，以确定其实用性。对所提出的SWB-MIMO天线在2 ~ 20GHz范围内的测试和仿真结果表明，该天线将是无线和生物医学应用的理想选择。

High Isolation Quad-Element SWB-MIMO Antenna with Dual Band-Notch for ISM and WLAN Band Wireless Applications

A quad-element super-wideband (2-20GHz) MIMO antenna including dual notched-band response at WiMAX (3.30-3.70GHz) and satellite-band (6.99-8.09GHz) is designed on RO3035 with total dimension of 118mm×86mm×1.67mm. Unique decoupling structure has been deployed to enhance the isolation (˃20dB) between two antenna elements. The fundamental properties of MIMO antennas like bandwidth ratio (10:1), isolation (>18dB), gain (4.14dB), Envelop Correlation-Coefficient (<0.0065), Total Active Reflection-Coefficient (< 0dB), Channel Capacity Loss (<0.25bps/Hz) and radiation patterns are also investigated in order to determine their practicality. Measurement and simulation results of the proposed SWB-MIMO antenna from 2 to 20GHz indicate that it will be the suitable candidate for wireless and biomedical applications.
