In this article, an eight-element, sixteen port dielectric resonator (DR) based double sided multi-port antenna is presented, which supports the unique dual-directional pattern diversity feature. The orientation of the double-sided dielectric resonator antenna (DRA) is one of the novel features of the proposed antenna. Four cylindrical dielectric resonator antennas (cDRAs) are placed at the top of the substrate, and each top cDRA is excited with the help of two orthogonally placed coplanar waveguide (CPW) fed conformal microstrip lines. In the same manner, the other four cDRAs are placed at the bottom of the substrate, and each cDRA is fed via conformal strip lines. The proposed antenna works in between 5.4 GHz and 6.0 GHz. Several isolation techniques (polarization diversity, pattern diversity, and separation between the antenna elements) within the antenna elements are approached to improve the antenna performance. As a result, without using any isolation improvement technique, the proposed structure achieves 17 dB of isolation between the ports, which makes the proposed radiator unique. The similarity in simulated and experimental outcomes confirms that the designed 16-port multi-port antenna system is suitable for Wireless LAN applications.

本文介绍了一种基于八元素，十六端口电介质谐振器（DR）的双面多端口天线，该天线支持独特的双向方向图分集功能。双面介质谐振器天线（DRA）的方向是所提出天线的新颖特征之一。四个圆柱形介质谐振器天线（cDRA）放置在基板的顶部，每个顶部cDRA借助两条正交放置的共面波导（CPW）馈入的共形微带线进行激励。以相同的方式，将其他四个cDRA放置在基板的底部，并且每个cDRA都通过保形带状线进料。拟议的天线工作在5.4 GHz至6.0 GHz之间。几种隔离技术（极化分集，模式分集，接近天线元件内的天线之间的距离和距离）以改善天线性能。结果，在不使用任何隔离改进技术的情况下，所提出的结构在端口之间实现了17 dB的隔离，这使得所提出的散热器独特。模拟和实验结果的相似性证实，设计的16端口多端口天线系统适用于无线LAN应用。
