Switchable Frequency Selective Surface Based on Polydimethyl-siloxane Composite Flexible Substrate for WLAN and 5G Sub-6GHz Applications

A switchable frequency selective surface (FSS) based on Polydimethyl-siloxane (PDMS) composite flexible substrate has been assessed by comparing it with its rigid counterpart is presented in this paper. To realize FSS as switchable, various switching combinations are investigated. The design demonstrates a stop-band and pass-band response. In pass-band it shows single wide band and dual band response. From the bending analysis of the proposed FSS, less variation are observed when the FSS sheet is bend along the H-field direction, whereas minor variations are observed when the FSS sheet is bend along the E-field direction. The flexible substrate design results show a good agreement with the rigid design and the added value of flexibility makes it suitable for 2.4GHz/5.8GHz WLAN and 5G sub-6GHz applications operating in 3.3-4.2 GHz and 4.5-4.9 GHz bands.
