Study Regarding the Tunability of a Frequency Selective Surface Having Incorporated Active Devices and Control Network

The demand for tunable devices in modern communication networks is rising. This article proposes a design for a tunable frequency selective surface which has two states (simulating ON and OFF states of PIN diodes). In order to bias the active parts, PIN diodes are employed as active devices for tuning and control networks incorporated in the structures. The suggested designs have been evaluated using electromagnetic simulation. Parametric studies are done to enhance the tunability of the proposed structures.
