Flexible PDMS Antenna Backed with Metasurface for 2.4GHz Wearable Applications

A PDMS based flexible antenna for 2.4GHz is presented. The proposed antenna is backed with metasurface based unit cells for reduction of SAR. Polydimethylsiloxane which is silicon based elastomers is used as flexible substrate, while copper sheet is used for conducting layers. The proposed antenna showing same band coverage around 2.4GHz in flat, bended and on body conditions. The simulated SAR value after placing on arm phantom model is 1.3W/Kg and 0.43W/ Kg in flat and flexible conditions which is less than the standard value 1.6W/Kg. so the proposed antenna can integrate to flexible electronic systems and a suitable candidate for wearable applications.
