Design and Analysis of an Implantable Dual-Band Antenna for Pancreas Biotelemetry

Abstract

This paper presents an implantable, miniaturized, dual band microstrip antenna for pancreas biotelemetry in the Medical Device Radiocommunications Service (MedRadio) band (401-406 MHz) and the Industrial Scientific and Medical ISM band (2.4-2.483 GHz). Miniaturization and dual band operation are achieved by inserting a shorting pin and two U-shaped slots on its conductive surface. The current density upon the surface of the antenna and resonance are evaluated to study the effect of design modifications on the antenna operation. In addition, reflection coefficient, adjustment of the input resistance and radiation performance are presented.
