Abstract

The invention discloses an intelligent omnidirectional surface. The intelligent omnidirectional surface comprises an intelligent surface array and a digital control module connected with the intelligent surface array; the intelligent surface array comprises a plurality of intelligent surface units; each intelligent surface unit comprises two surface layers which are arranged in a mirror symmetry manner; each surface layer comprises a substrate and a diode arranged on the substrate; each intelligent surface unit is connected with the digital control module; and the digital control module is used for controlling the bias voltage of each intelligent surface unit so as to change the reflection phase and the transmission phase of the intelligent surface unit. According to the invention, wireless coverage at two sides can be expanded, so that the coverage range is expanded.

Description

technical field [0001] The invention relates to the field of intelligent surfaces, in particular to an intelligent omnidirectional surface. Background technique [0002] At present, most of the smart surfaces are reconfigurable smart surfaces. When the reconfigurable smart surface is placed in the wireless network and used as a part of the wireless communication environment, although the purpose of extending wireless coverage can be achieved, due to the reconfigurable Each unit on the smart surface has either a reflectance close to 0 or a transmittance close to 0, so only one side of the wireless coverage can be extended. Taking the reflectivity of 0 as an example, when the receiver is located in the reflection area, since the signals incident on the units of the reconfigurable smart surface will not be reflected, the signals received by the receiver are the same as the original ones, so The coverage is not expanded; and when the receiver is located in the transmission area...
