摘要

提出了一种在WLAN上层应用频段同时具有方向图和极化分集(线性/圆形)的紧凑型双元多输入多输出(MIMO)天线系统。所设计的天线系统由一个倒角边缘偏置馈电方形贴片天线和一个相邻的印刷偶极子天线组成，该天线在宽方向上提供圆极化(CP)，并具有线极化(LP)的火端辐射。因此，可以同时实现模式分集和极化分集(LP/CP型)，并且具有良好的隔离性，不需要单独的解耦机制。天线总占地面积为0.54 λ0 × 0.63 λ0，其中λ0为5.66 GHz的自由空间波长。在天线样机上的实测结果与全波仿真结果吻合较好。

A compact two element MIMO antenna system for pattern and polarization diversity

In this paper, a compact two-element Multiple Input Multiple Output (MIMO) antenna system having simultaneous pattern and polarization diversity (linear / circular) in upper WLAN application band is proposed. The designed antenna system consists of a chamfered edge offset fed square patch antenna providing circular polarization (CP) in broadside direction and an adjacent printed dipole antenna having linearly polarized (LP) end-fire radiation. So, pattern diversity and the polarization diversity (LP/CP type) are achieved simultaneously with good isolation, without the requirement of any separate decoupling mechanism. The overall antenna footprint is 0.54 λ0 × 0.63 λ0, where λ0 is the free space wavelength at 5.66 GHz. The measured results on a fabricated prototype of the proposed antenna match reasonably well with the full-wave simulation results.
