Abstract
This paper is devoted to the study and design of flexible and transparent antenna encased inside a soft smart contact lens for medical diagnostics operating in the Industrial, Scientific, and Medical (ISM) band (5.83GHz). The proposed antenna is based on the integration of conductive transparent graphene on a bio-compatible polymer substrate with thickness of 0,25 mm and dielectric constant of approximately 2,65. The antenna dimensions and its performance are determined using CST simulator. Good results in terms of S11 (−35.13dB), gain (2.91dB), directivity (3.02dBi), bandwidth (8.06%) and efficiency (96.35%) are reached. Significant gain improvement is observed when integrating graphene as contact lens antenna, as compared to a reference antenna made from gold.
