An angular‐stable multi‐layer reconfigurable frequency selective surface (FSS) based on varactor with wide tuning range is proposed in this article. The working principle of the FSS is analyzed by the equivalent circuit model (ECM). By tuning the DC bias voltage applied to the varactors loaded on the top and bottom layers, the pass band of the FSS can be located in the C, X, and Ku band respectively with a wide reconfigurable range. In addition, due to the introduction of the miniaturized structure and the four metal vias in Z ‐direction, the FSS provides good angular stability under TE and TM polarization. Finally, the fabrication and experiment are provided to verify the validity of the reconfigurable FSS.
