Miniaturised dual-band implantable antenna for wireless biotelemetry

Abstract

A miniaturised implantable antenna with dual-band operation the Medical Implant Communications Service (MICS) (402-405 MHz) and Industrial, Scientific, and Medical (ISM) (2400.0-2483.5 MHz) bands is presented. The size of the proposed antenna is 31.5 mm(3) (8.75 mm x 7.2 mm x 0.5 mm) which is the smallest size compared to previous implantable antennas. A serpentine-shaped radiating patch and open-end slot placed on the ground plane are used for miniaturisation. The performance of the antenna was evaluated from measurements and is based on good agreement with simulations.
