==ACTIVE METASURFACE UNIT CELL WITH DUMMY PATTERN TO MAINTAIN A CONSTANT PHASE DIFFERENCE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240129752 titled 'ACTIVE METASURFACE UNIT CELL WITH DUMMY PATTERN TO MAINTAIN A CONSTANT PHASE DIFFERENCE

==Simplified Explanation==

The patent application abstract describes a reconfigurable intelligent surface (RIS) for a 5G or 6G communication system that enables a low phase error at various incidence angles/reflection angles. The RIS includes unit cells with adjustable reflection phases, switches to control these phases, and dummy patterns for multiple unit cell arrangements.

* RIS for high data transmission rate support:
  - The RIS is designed to support a higher data transmission rate in a 5G or 6G communication system.
  - It enables a low phase error at different angles of reflection, improving signal quality.

* Unit cells with adjustable reflection phases:
  - The unit cells in the RIS are configured to adjust the reflection phase, allowing for precise control over signal reflection.
  - This feature helps optimize signal strength and quality in the communication system.

* Switches for phase adjustment:
  - Switches are operably connected to the unit cell pattern, providing a mechanism to adjust the reflection phase as needed.
  - This flexibility allows for real-time adjustments to optimize signal performance in varying conditions.

* Dummy patterns for multiple unit cell arrangements:
  - Dummy patterns are included between unit cell patterns when multiple unit cells are arranged, ensuring proper spacing and signal reflection.
  - This design feature helps maintain signal integrity and performance in complex RIS configurations.
