Abstract

Abstract In this paper, a Decoupling Nearfield Surface (DNS) is designed above the antenna, to reduce the mutual coupling of closely two or more patch array. In this way, the electrical and magnetic distributions are utilized to demonstrate the mechanism of isolation. The proposed DNS element creates the electric field distributions with an orthogonal mode and the magnetic field distributions with excitation in substrate such that the effective suppression of antenna mutual coupling is obtained. The DNS element can be easily applied to the Multiple-Input Multiple-Output (MIMO) antennas that having multiple patch elements. Moreover, the proposed structure is implemented practically and simulated for a patched antenna. The measurement and simulation results verifies that the isolation is more than 20 dB and the isolated impedance bandwidth is about 7%.

MIMO贴片天线Peyton-Turtle模式近场表面的互耦抑制

摘要本文在天线上方设计了一种解耦近场表面（DNS），以减少两个或多个紧密贴片阵列的相互耦合。通过这种方式，利用电场和磁场分布来证明隔离的机制。所提出的DNS元件在衬底中创建具有正交模式的电场分布和具有激励的磁场分布，从而获得天线互耦的有效抑制。DNS元件可以容易地应用于具有多个贴片元件的多输入多输出（MIMO）天线。此外，还对所提出的结构进行了实际实现，并对贴片天线进行了仿真。测量和仿真结果表明，隔离度大于20dB，隔离阻抗带宽约为7%。

期刊介绍： Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
