Abstract

The design of low-profile Multiple-Input-Multiple-Output (MIMO) antennas for various 5G applications is a topic of huge interest in academia, research, and telecommunication sector. In this aspect, a compact and low-profile 5G MIMO antenna has been designed and analyzed for various 5G applications, specifically for the 24 GHz bands (24.25–24.45 GHz and 25.05–25.25 GHz) and local multipoint distribution system band (27.5–28.35 GHz) of the 5G spectrum. The proposed antenna structure is 20 × 20 × 1 mm3 in dimension. Two spade-shaped radiators composed of Copper (annealed) material are placed orthogonally to improve isolation and maintain signal diversity. Rogers RT 5880 is used as the material for substrate. The antenna exhibits a wide bandwidth of 21.5–28.5 GHz. The mutual isolation |S21| has been maintained ≤29 dB due to the insertion of a T-shaped parasitic strip in between the radiating elements. Novelty in design and superiority in performance has been observed when compared with related antenna categories.

设计、制造和测量适用于 5G 通信的小型化多输入多输出天线

为各种 5G 应用设计扁平式多输入多输出 (MIMO) 天线是学术界、研究领域和电信部门非常感兴趣的一个课题。在这方面，针对各种 5G 应用，特别是 5G 频谱中的 24 GHz 频段（24.25-24.45 GHz 和 25.05-25.25 GHz）和本地多点分配系统频段（27.5-28.35 GHz），设计并分析了一种紧凑、扁平的 5G MIMO 天线。拟议的天线结构尺寸为 20 × 20 × 1 mm3。两个由铜（退火）材料组成的铲形辐射器正交放置，以提高隔离度并保持信号分集。基板材料采用罗杰斯 RT 5880。天线的带宽为 21.5-28.5 GHz。由于在辐射元件之间插入了 T 型寄生条，因此相互隔离度 |S21| 保持在 ≤29 dB。与相关天线类别相比，该天线设计新颖，性能优越。
