面向2.4 GHz工业场景的轻薄低损耗反射补偿型智能反射面
A Lightweight and Low-loss Reflection Compensation-type Intelligent Reflection Surface for 2.4 GHz Industrial Scenarios
摘要
Abstract
For the problem that the existing high-frequency band intelligent reflection surface(IRS)cannot meet the low cost and high reliability requirements of industrial applications,a lightweight and low-loss reflection compensation IRS is designed for 2.4 GHz industrial scenarios.A non-perforated metal layer structure is proposed.By adjusting the positions of the ground layer and bias layer,perforations are avoided,and electromagnetic energy loss is reduced.The top-layer patch is designed to form a three-piece symmetrical structure,which maximizes the resonance range of the two tunable devices,which effectively reduces the energy loss of the incident signal and provides sufficient phase span.The simulation results show that the reflection amplitude loss of the designed 2 mm thick IRS is less than 1.6 dB,and the reflection phase span is 296°.Compared with that of the existing prototype that can be applied to the 2.4 GHz frequency band,the reflection amplitude is increased by 61.9％at the same phase,and the reflection phase is increased by 5 times at the same amplitude.In addition,the designed prototype has high phase adjustability and stability.关键词
