  • A 1-bit reconfigurable intelligent metasurface-based antenna for 5G application is proposed. The proposed antenna based on artificial electromagnetic metamaterial has the advantages of easy processing and low cost. This meets the requirements of future communication network development. This antenna shows that the unit cell has a stable 180° phase difference between the ON and OFF states by loading a PIN diode at 6.425–7.125 GHz. A 10 × 10 array antenna is constructed by using 2 × 2 meta-atoms to reduce the complexity of the control network. This proposed antenna can achieve ±40° beam scanning with a gain tolerance of 3 dB and a maximum gain of 18.7 dBi. In addition, beamforming performance, such as multi-beams, is also achieved. These properties ensure that the proposed antenna has great potential in wireless communication systems and microwave imaging systems.
