Abstract

A compact dual-band Multiple-Input Multiple-Output Dielectric Resonator Antenna with improved bandwidth for 5G mm-wave applications is presented. Two rectangular DRAs mounted on a substrate backed ground plane are excited by microstrip feed through aperture coupling. Notches cut out from center of the DRAs helps to achieve a dual-band response with improved bandwidth by exciting several modes. The isolation between the DRAs is achieved by appropriately positioning metallic strips on walls on of the DRAs. A dual-band response with enhanced bandwidth and mutual coupling reduction. The impedance bandwidth for the proposed design is between 26.5–30 GHz (12.4 %) and 34.2–40 GHz (15.6 %). The maximum isolation achieved in the lower band is 32 dB and above 45 dB in the upper band. The overall size of the design is 1.88λ_o x 0.94λ_o x 0.20λ_o. The design procedure is described, and the role of decoupling strips are explained. A prototype is fabricated and measured to validate the proposed design.

利用金属带的紧凑型双频增强带宽 5G 毫米波 MIMO 介质谐振器天线

本文介绍了一种紧凑型双频多输入多输出介质谐振器天线，它具有更高的带宽，适用于 5G 毫米波应用。两个矩形介质谐振器安装在一个基底面上，通过孔隙耦合由微带馈电激励。从 DRA 中心切出的凹槽有助于实现双频响应，并通过激发多种模式提高带宽。DRA 之间的隔离是通过在 DRA 壁上适当放置金属条来实现的。双频响应，带宽增强，相互耦合减小。拟议设计的阻抗带宽介于 26.5-30 千兆赫（12.4%）和 34.2-40 千兆赫（15.6%）之间。低频段实现的最大隔离度为 32 dB，高频段超过 45 dB。设计的总体尺寸为 1.88λo x 0.94λo x 0.20λo。介绍了设计程序，并解释了去耦条的作用。制作并测量了一个原型，以验证所提出的设计。
