Abstract :
The proposed antenna is designed & simulated in Med-Radio band with finite element method (FEM) based high frequency structure simulator (HFSS) solver & fabricated for intraocular application for transceiver. This six layer antenna is encapsulated with poly dimethyl siloxane (PDMS) & entire antenna has been implanted inside the phantom of spherical vitreous humor at the size of human eyeball. The reflection coefficient of -30.13dB, -10dB bandwidth of 63.66 MHz, gain of -24.32 dB, 1 gm averaged SAR on vitreous body of 0.265 W/kg at incident power of 0.49 mW, reduction in size by 48% & very high efficiency of 6.90 % at resonant frequency of 403 MHz are obtained.
