Active Frequency Selective Surface with Wide Reconfigurable Passband
2020
An active frequency selective surface (AFSS) with wide reconfigurable passband is proposed in this paper. The AFSS adopts compact arrangement, fractal gap introduced, symmetry design and the integrated design of the bias network. The simulation results show that the AFSS obtain a reconfigurable passband ranged from 9.6 to 12.7 GHz by variable diodes. At the same time, it maintains a consistent insertion loss, -3dB bandwidth, polarization stability and angle stability during tuning.
