Abstract

This paper presents the design guidelines, simulation and measured results of implantable spiral chip inductor/radiator, passive sensor, and external planar multi-turn loop antenna for a wireless blood pressure monitoring system operating in the range 190-203 MHz. A new approach to the design of planar multi-turn loop antenna has been presented. Also included are the measured transmission characteristics of the RF signal through air as well as air and phantom tissue. The measurements demonstrate that the RF signal can penetrate through human tissue with acceptable attenuation.
