Abstract
In this work, we propose a loaded diode frequency reconfigurable ultra-thin metasurface for beam switching. Different bias voltages are applied to the ultra-thin reconfigurable unit to achieve different phase gradients between adjacent units in the x-axis direction. Different voltage configurations are used to achieve stable phase gradient in different working frequencies which ensures the stability of beam scanning and expands the operating bandwidth of the antenna. The characteristics of frequency reconfigurable metasurface have been verified over the frequency band 9.1-10.1 GHz. This study paves a novel strategy of bandwidth expansion with the advantages of reconfigurable frequency and lightweight.
