Summary:
A reconfigurable frequency selective surface (FSS) is presented in this paper. The tunable FSS is based on a common FSS comprising annular ring slot and cruciform structure cells. The tuning of the reconfigurable surface is shown numerically to be possible by incorporating tuning varactors into the structure. Using varactors on both layers, a reconfigurable frequency response is achieved, which has three modes of center frequency. Numerical simulations show that lower and upper frequency can be tuned separately by altering the capacitance of the loaded varactors. So that multiple-band frequency response is electronically tunable separately. Besides that, the FSS is stable with different polarizations and incident angles.
