摘要

本文提出了一种新的MIMO天线间的解耦技术，其边缘间距为0.03λ (1.975mm)。在天线之间使用微带谐振器作为去耦装置。MIMO以其提高的数据传输速率在当前通信系统中发挥着重要的作用。然而，近距离MIMO天线的主要缺点是高互耦性。MC会影响MIMO天线的整体特性，从而导致天线的性能下降。为了克服这个问题，我们引入了一个微带谐振器，作为MIMO天线之间的电墙。利用IE3D仿真器对该天线进行了仿真，在4.85 GHz谐振频率下实现了48dB的MC抑制。制作了MIMO天线，并与仿真结果进行了比较。该天线可用于无线通信、WLAN和卫星通信。

Study of Decoupling between Closely Spaced Microstrip MIMO antennas using Microstrip Resonator

This paper presents a novel decoupling technique between two closely spaced MIMO antennas whose edge to edge spacing is0.03λ (1.975mm).A microstrip resonator is used in between the antennas that act as a decoupled device. The MIMO plays an important role in the current communication system due to its enhanced data transferring rate. However, the closely spaced MIMO antennas have a major disadvantage of high mutual coupling (MC). MC affects the entire characteristics of MIMO antennas and as a result, the performance of the antenna degrades. To overcome this problem, we have introduced a microstrip resonator that acts as an electrical wall between the MIMO antennas. The antenna has been simulated by using an IE3D EM simulator and a suppression of 48dB MC is achieved at a resonant frequency of 4.85 GHz. The MIMO antennas have been fabricated and the results are compared with the simulated ones. This antenna can be used in wireless communication, WLAN and satellite communication.
