Finally, the proposed metasurfaces help the millimeter-wave base station to realize real-time information transmission of multi-users with different directions in a realistic indoor scenario. The experimental results demonstrate that the new beamforming base station system can intelligently enhance or attenuate signals in specific target areas.
Here, we propose a large-scale 2-bit millimeter-wave programmable metasurface to build an integrated smart base station framework for 6G communications. The meta-array is composed of 30 × 30 meta-elements, each with two embedded positive-intrinsic-negative (PIN) diodes.
The simulation and experimental results indicate that the designed large-scale metasurface possesses 2-bit phase-modulation capability in the millimeter-wave band and achieves a wide beam-scanning range in free space (–70° ≤ θ ≤ 70°, 0° ≤ φ ≤ 360°) with a gain of 23 dBi.
In , a 2-bit transmissive RIS design with a 90° digital phase shifter and a 1-bit vertical current reversible dipole was presented to work in millimeter-wave bands, which aids wireless communications. However, low integration, high profile and bulky feed structures make most of the above metasurfaces inflexible for applications.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
