Abstract

A framework of a metasurface (MTS) – based wideband circularly polarized (CP) reconfigurable antenna for fifth generation (5G) wireless systems operating in the sub-6 GHz mid-frequency range is presented in this article. The proposed structure contains a simple patch antenna, which serves as the primary source, a shorting pin, two ring slots, and a metasurface superstrate. The shorting pin and two ring slots produce perturbation resulting in circular polarization with a narrow axial ratio (AR) bandwidth. A metasurface (MTS) superstrate composed of 4 × 4 rectangular patches stacked over the primary source antenna generates additional resonances that significantly improve the −10 dB impedance and 3 dB axial ratio (AR) bandwidth. Two PIN diodes are employed to alter the circular polarization between left-hand circular polarization (LHCP) and right-hand circular polarization (RHCP). The prototype is made using an FR-4 epoxy substrate and has an overall size of 50 mm × 35 mm × 4.2 mm. The antenna has a −10 dB bandwidth of 44 % (4.0–6.2) and a 3 dB axial ratio bandwidth of 28 % (4.2–5.6). It also has a 3 dB beam width of 74° and 85° in the E and H planes, a gain of 7.1 dBi, cross-polar isolation of more than 15 dB, and a unidirectional radiation pattern. The simulated and measured results confirm that the implemented antenna is promising for sub-6 GHz 5G communication systems, particularly cognitive radio, wireless body area networks (WBAN), and satellite communication systems.

用于 5G 应用的宽带圆极化可重构元面天线
本文介绍了一种基于元表面(MTS)的宽带圆极化(CP)可重构天线框架,适用于工作在 6 GHz 以下中频范围的第五代(5G)无线系统。所提出的结构包含一个作为主源的简单贴片天线、一个短路引脚、两个环形槽和一个元表面叠层。短路引脚和两个环形槽产生扰动,从而产生具有窄轴向比(AR)带宽的圆极化。元表面 (MTS) 叠层由 4 × 4 矩形贴片组成,堆叠在主源天线上,产生额外的谐振,显著改善了 -10 dB 阻抗和 3 dB 轴向比 (AR) 带宽。采用两个 PIN 二极管在左手圆极化 (LHCP) 和右手圆极化 (RHCP) 之间改变圆极化。原型使用 FR-4 环氧树脂基板制作,总尺寸为 50 mm × 35 mm × 4.2 mm。天线的 -10 dB 带宽为 44 %(4.0-6.2),3 dB 轴向比带宽为 28 %(4.2-5.6)。此外,它在 E 平面和 H 平面的 3 dB 波束宽度分别为 74° 和 85°,增益为 7.1 dBi,跨极隔离度超过 15 dB,辐射模式为单向。模拟和测量结果证实,所实现的天线有望用于 6 GHz 以下的 5G 通信系统,特别是认知无线电、无线体域网 (WBAN) 和卫星通信系统。

期刊介绍: Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
