摘　　要：A new technique of designing a dual-band frequency selective surface with large band separation is presented.This technique is based on a delicately designed topology of L-and Ku-band microwave filters.The two band-pass responses are generated by a capacitively-loaded square-loop frequency selective surface and an aperture-coupled frequency selective surface,respectively.A Faraday cage is located between the two frequency selective surface structures to eliminate undesired couplings.Based on this technique,a dual-band frequency selective surface with large band separation is designed,which possesses large band separation,high selectivity,and stable performance under various incident angles and different polarizations.A new technique of designing a dual-band frequency selective surface with large band separation is presented.This technique is based on a delicately designed topology of L-and Ku-band microwave filters.The two band-pass responses are generated by a capacitively-loaded square-loop frequency selective surface and an aperture-coupled frequency selective surface,respectively.A Faraday cage is located between the two frequency selective surface structures to eliminate undesired couplings.Based on this technique,a dual-band frequency selective surface with large band separation is designed,which possesses large band separation,high selectivity,and stable performance under various incident angles and different polarizations.
