With the advantage of programmable electromagnetic properties, Reconfigurable Intelligent Surfaces (RISs) have drawn wide attention from both industry and academia. RIS-assisted communication systems can promote huge wireless channel quality improvement and remarkable coverage enhancement. This paper proposes general pathloss model, radiation pattern and mirror beam effect of 1-bit RIS at sub-6 GHz band. Field trails have been carried out in outdoor and indoor deployment scenarios. The proposed model is validated through extensive simulations and field-trial measurements. In addition, an optimized RIS phase-shit design process for the mirror beam elimination is proposed and validated with simulations. The proposed theoretical model and measurement results can promote future research and application in RIS-assisted communications. |
