摘要

本文设计了一种采用中和线提高隔离度的双频MIMO天线。所述低频谐振单元为倒F天线，并添加另一根以产生更高的频率。在现有天线之间蚀刻一条中和线以改善隔离。仿真结果表明，该天线的工作频段分别为2.39GHz-2.53GHz和4.57GHz-6.09GHz。天线两个端口之间的隔离在低频S21< -19.3dB，在高频S21< -24.6 dB。满足无线局域网通信的要求。

Dual Frequency MIMO Antenna with Neutralization Line

In this paper, a dual frequency MIMO antenna using a neutralization line to improve isolation is designed. The lower frequency resonant unit is an inverted F antenna and another stub is added to generate higher frequency. A neutralization line is etched between the present antennas to improve the isolation. The simulation results show that the two operating bands of the antenna are 2.39GHz-2.53GHz and 4.57GHz-6.09GHz. The isolation between the two ports of the antenna is S21 < -19.3dB in the low frequency band, and S21< -24.6 dB in the high frequency band. It is meet the requirements of the WLAN communication.
