摘要

这项工作提出了使用反射面板作为一种高效、低成本的解决方案，以提高5G场景下毫米波的覆盖范围。双偏振异形光束被设计成辐射平顶光束以覆盖无覆盖的盲区。考虑到室外场景的光束规格，该设计使用纯相位合成进行。然后，采用单层反射元件在27.7 GHz频段进行设计。该元件在工作频率下提供角稳定的相位响应，在每个线偏振中具有独立的相位控制。反射面板显示出稳定的增益，在1ghz带宽内具有较低的副瓣电平和交叉极化。

Reflectarray-based Intelligent Reflecting Surface to Improve mm-Wave 5G coverage in outdoor scenarios

This work presents the use of a reflectarray panel as an efficient and low-cost solution to improve millimeter-wave coverage in 5G scenarios. A dual-polarized shaped-beam is designed to radiate a flat-top beam to cover a blind zone without coverage. The design is carried out using a phase-only synthesis considering the beam specifications for the outdoor scenario. Then, a single-layer reflectarray element is used to perform a design at 27.7 GHz. This element provides an angularly-stable phase response at the operational frequency with an independent phase control in each linear polarization. The reflectarray panel shows a stable gain and a low both side-lobe level and cross-polarization within 1 GHz bandwidth.
