Reconfigurable Low Sidelobe Antenna Design with Amplitude and Phase Simultaneous Modulated High Efficiency Metasurface

In this work, metasurface is utilized to realize the reconfigurable low sidelobe antenna. The amplitude and phase of the transmitted wave can be controlled by metasurface unit. The metasurface unit cell operates in PB mode and its efficiency can reach 0.9. The needed amplitude distribution is calculated by Taylor synthesis algorithm. The simulated and calculated sidelobe level both agree well to our design goal.
