The FSR with wide transmission band is realized by introducing a resistance layer above the bandpass FSS. The resistance layer is designed on the upper surface of the dielectric substrate and consists of a resistance film with a square structure, which provides the absorbing properties at high-frequency band. The bandpass FSS layer is designed on the upper and lower surfaces of the dielectric substrate, and four metal vias are introduced to connect the top and bottom structures together, providing good transmission properties at the low-frequency band. The designed FSR can provide a wide −3 dB bandwidth of 101% in the 1.73~5.25 GHz, and the −10 dB absorbing properties is achieved in the 8.31~12.14 GHz. Meanwhile, the structural dimension of the unit is about 0.03$\lambda \times 0.03\lambda$ ($\lambda$ being the central frequency of the transmission band) so that the good angular stability is obtained.
