Abstract

The embodiment of the invention provides an adjustable electromagnetic array element and an intelligent surface. The adjustable and controllable electromagnetic array element comprises a reflecting unit and a parasitic unit. The reflecting unit comprises at least one reflecting metal sheet; and at least one adjustable element which is electrically connected with the reflecting metal sheet, and is used for adjusting the electromagnetic parameters of the electromagnetic array element according to an adjusting signal. The parasitic unit is arranged at the periphery of the reflecting metal sheet and is coupled to the reflecting metal sheet. According to the embodiment of the invention, the parasitic unit is arranged at the periphery of the reflecting unit of the adjustable electromagnetic array element to form a parasitic intelligent surface, and the constitutive parameters of the intelligent surface are changed through the coupling effect between the parasitic unit and the electromagnetic array element, so that the reflection loss of the intelligent surface is reduced, the phase response stability of the intelligent surface is improved, the performance limitation of the array element layout and the dielectric substrate on the intelligent surface can be broken through, and the reliability of a multi-bit multi-polarization RIS scheme is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of wireless communication, and in particular to controllable electromagnetic array elements and smart surfaces. Background technique [0002] As one of the important technologies of wireless communication, RIS (Reconfigurable Intelligent Surface) has been valued by the industry. RIS can form a specific beam pointing by controlling the electrical parameters of the electromagnetic array element, so as to achieve signal blindness compensation or enhancement in the required area. The reflective RIS can realize the signal coverage of the base station's line-of-sight blind area, so its application potential is huge. Reflective RIS can be divided into 1-bit and multi-bit according to the number of phase states of the reflected electromagnetic wave; it can be divided into single-polarization and multi-polarization according to the polarization characteristics of the reflected wave; it ca...
