摘要

本文研究了一种适用于MIMO的高隔离圆柱介质谐振器天线(DRA)。通过两个不同的端口实现高隔离。MIMO天线由一个圆柱形介质谐振器天线组成，该天线由两条不同极化的馈线馈电，用于正交模式激励。端口1和端口2的阻抗带宽分别为12.8% (3.17-3.6 GHz)和14.09% (3.1-3.57 GHz)。两个端口之间的隔离度在工作频带内优于−27dB。采用s参数法计算包络相关系数(ECC)、分集增益(DG)、平均有效增益(MEG)等MIMO性能参数，对天线进行了检验。该天线适用于WiMax应用。

A high isolation cylindrical dielectric resonator antenna for MIMO application

In this paper, a cylindrical dielectric resonator antenna (DRA) with high isolation is investigated for MIMO applications. High isolation is achieved with the help of two different ports. The MIMO antenna consists of a cylindrical dielectric resonator antenna which is fed by two differently polarized feed lines for orthogonal mode excitation. The impedance bandwidth for port 1 and port 2 is 12.8 %(3.17–3.6 GHz) and 14.09 % (3.1–3.57 GHz) respectively. The isolation between the two ports is better than −27dB in the operating frequency band. The presented antenna is examined by calculating various MIMO performance parameter such as envelope correlation coefficient (ECC), diversity gain (DG), mean effective gain (MEG) by using S-parameter. The proposed antenna is suitable for WiMax applications.
