Holographic metasurface design for flexible beamforming antennas

The paper presents a novel approach to designing holographic metasurfaces tailored for flexible beamforming antennas. Leveraging the unique properties of a flexible Rogers substrate with a thickness of 0.5 mm, the proposed metasurface enables versatile beamforming capabilities while maintaining mechanical flexibility. Specifically, the design focuses on achieving a focused beam at an angle of 12" at 14.5 GHz. Through rigorous electromagnetic simulations and optimization, the metasurface is engineered to exhibit precise phase modulation and impedance matching, ensuring efficient beam steering and radiation control. The designed antenna system demonstrates impressive performance, achieving a substantial gain of approximately 13 dBi.
