Polydimethylsiloxane Based Reconfigurable Intelligent Surfaces Loaded Flexible Antenna for Pattern Reconfigurable Applications

Year: 2024

Type: conference-paper

Abstract: This study proposes the design of Polydimethylsiloxane (PDMS) based semi-transparent flexible antenna system for omni-directional to directional pattern reconfigurable applications.The system comprises of a compact antenna resonating at 3.5 GHz which is loaded with an reconfigurable intelligent surface (RIS) controlled by PIN diodes.Both antenna and RIS are made up of 1mm thick PDMS substrate, a highly flexible and transparent material, while radiator of proposed system is made using copper with a thickness of 0.035mm.The RIS backed antenna offers omni-directional radiation pattern when all switches are off-state, resulting in in-activation of RIS.On the other hand, a broadside radiation pattern is achieved when the switches are turned ON, corresponding to activation of RIS.Conformal analyses are also carried out by cylindrical bending across the X-and Y-axis, along with that the SAR analysis are performed to validate the suitability of proposed work for on-body applications.
