Parametric study and design of implantable PIFAs for wireless biotelemetry

Abstract

The design parameters of a skin-implantable planar inverted-F antenna (PIFA) operating in the 402-405 MHz Medical Implant Communications Service (MICS) band are studied and their impact on the exhibited resonance characteristics is assessed. Based on the parametric results, two novel MICS PIFAs are proposed for skin-implantation. The study, thus, evaluates the tuning stability of a novel implantable PIFA on potential manufacturing inaccuracies. Significant guidance on implantable PIFA design is also provided. Numerical results based on Finite Element Method (FEM) numerical simulations are presented. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
