AB  - With the continuous advancement of technology, there is an increasing need for 
      innovative solutions that can handle complex applications such as haptic 
      communications, Internet of Things for smart cities, automation, and 
      manufacturing. One technology that has received much attention is the phase 
      reconfigurable metasurface for reconfigurable intelligent surfaces (RISs). The 
      RIS demands low-power consumption, simple configuration, angular stability, and 
      polarization insensitivity. The use of phase reconfigurable metasurfaces provides 
      benefits such as low cost, low power consumption, and improved communication 
      coverage and quality. This article introduces a reconfigurable combined-loop 
      metasurface that can effectively manipulate phase reflection. This is achieved by 
      incorporating four PIN diodes between two meta-atoms of a 2 x 2 periodic array 
      within a single-layer metallic structure. By controlling the state of the PIN 
      diodes, which can be switched into 16 different states, the metasurface can 
      achieve various phase reflections. The proposed structure has validated a 32x 32 
      metasurface through numerical simulations and experiments that exhibit promising 
      results, demonstrating its potential for use in 6G applications.
