| Summary: | Abstract In this work, a reconfigurable frequency-selective surface (FSS) with a very simple biasing network that offers singleor multi-band response is presented. The proposed structure is formed by the V-shaped elements on a single-sided dielectric substrate. A PIN diode is used as active device to make the FSS reconfigurable, and bias lines are inserted for feeding. Initial analysis is performed with passive FSSs to predict the behavior of the proposed reconfigurable structure. The proposed reconfigurable FSS is then designed and evaluated. Three biasing-state configurations are analyzed: off-state, on-state, and intermediate-state. Depending on the state applied to the FSS, it can exhibit single switchable resonance frequency or multi-band response with a Fano resonance. |
