A paper‐based uniplanar ultra‐wideband (UWB) frequency‐selective surface (UWB FSS) design was developed to achieve UWB radar signal cut‐off. The proposed structure includes a unit cell combining a square‐loop structure and fan‐blades structure arranged on a 0.2 mm‐thick paper. Resistive ink was used to introduce a resistive element, thereby securing incident angle stability. To verify the performance of the designed structure, a screen‐printing method was used to introduce the conductive patterns and resistive element. The free‐space measurement showed that the vertical incident wave has wideband characteristics of 4.5 to 11.4 GHz at −10 dB blocking, with relatively stable polarisation and incident angle stability.
