| Abstract | The dependency on feed horn of the metasurface leads to an increased physical profile and energy dissipation, posing challenges to system miniaturization and integration. To tackle this problem, a metasurface antenna with a low profile, fast programmability, and flexible wavefront reconfiguration capability is proposed. By integrating the transmissive metasurface with a planar array antenna, a 4.64λ0 × 4.64λ0 antenna operating over 5.77–5.83 GHz is realized with a thickness of 0.54λ0. The planar feeding design reduces the total antenna height by approximately 99% compared to the conventional programmable metasurface. The experimental results have demonstrated that the presented antenna can achieve ±60◦ beam steering. In addition, a simple antenna-based wireless communication platform is established, allowing for direct nonlinear harmonic modulation and information transmission without mixing devices. The proposed programmable metasurface antenna opens a new avenue to advance compact and efficient applications across diverse fields, including satellite communications, IoT devices, and smart city infrastructure. © 1963-2012 IEEE. |
