A frequency selective surface with a new type of three‐dimensional element which produces a quasi‐elliptic bandpass response is presented. The element exhibits an elliptic bandpass response with a −3 dB bandwidth (BW/ f 0 ) of ∼ 70%, where f 0 is the centre frequency. The design has been adapted to a form that can be conveniently fabricated by utilising printed technology. The measured results for the frequency response show good agreement with those predicted via numerical simulations.
