A miniaturized frequency selective rasorber (FSR) with high selectivity passband and wideband absorption properties is presented. Its performance as an absorber over a wide absorption band from 8.08 to 18.08 GHz through the structure of metal incurved square loop structure loaded resistors. The frequency selective surface (FSS) using Jerusalem cross array and metallic patch realizes the transmission frequency band from 2.7 to 3.52 GHz. And the insertion loss (IL) is 0.37 dB at 3.08 GHz.
