Coil Shape Antenna Design To Enhance The Performance Of 1 Pair Capacitive Coupling For Implant Medical Device Application

This paper introduces a method to increase capacitive coupling between transmitter antenna and receiver antenna using coil shape design and a method to reduce the traditional 2 pairs capacitive coupling to 1 pair coupling by using different equipotential zone to allow current circulation in receiver circuit. The performance of the proposed methods had shown better capacitive coupling than using sheet plate and constant coupling in distance misalignment.
