Miniaturized Implantable Coplanar Waveguide Antenna for Biomedical Applications

Abstract

Implanting electronic devices in the human body is a delicate operation that can be hazardous and of negative consequences. Such implantable devices must be safe and small without sacrificing their performance characteristics, namely their efficiency and accuracy. This paper presents, the design, simulation, fabrication, and validation of small antenna implementation suitable for implanting in the human body. The development comprises small CPW feed antenna that can operate around 1.4 GHz standard Wireless Medical Telemetry Service (WMTS) band, with an ability to tune the frequency by merely varying the length of the monopole antenna. The behavior of the designed antenna thoroughly analyzed under a state-of-the-art simulator. The effectiveness of the fabricated antenna ensured through extensive in vitro tests and comparisons with the response obtained through simulations. The results confirm the successful development of small and implantable antenna with appealing performance characteristics.
