A reconfigurable electromagnetic shield by active frequency selective surface (AFSS) with switch function at LTE-D 4G mobile communication is proposed in this paper. Double coupled metallic meandered structures on one layer substrate loaded PIN diodes are designed carefully to realize the band-pass characteristic at 2.6GHz when PINs are OFF and the rejection characteristic when PINs are ON. The proposed...
In this letter, a simple design method for reconfigurable active frequency selective surface (AFSS) and novel switchable AFSS is presented, which the AFSS can transmit LTE 2.1 GHz signals in PIN‐OFF state while function as a band‐stop filter to shield those signals in PIN‐ON state. Compared with regular square loop AFSS, the proposed structure is exhibited fair stability for different incident angles...
