New Flexible Medical Compact Antenna : Design and Analysis

Abstract EN

Some results on embedded antennas for medical wireless communication systems are presented.

Medical telemetry can advantageously assist medical diagnostics.

For example, you can better locate a diseased area by monitoring temperature inside the human body.

In order to establish efficient wireless links in such an environment, a special attention should be paid to the antenna design.

It is required to be of a low profile, very small regardless of the working frequency—434 MHz in the ISM band, safe, and cost effective.

Design of the as-considered antenna is proposed based on a simple model.

The approach has been demonstrated for a compact flexible antenna with a factor of 10 with respect to the half-wave antenna, rolling up inside an ingestible pill.

Measured and calculated impedance behaviour and radiation characteristics of the modified patch are determined.

Excellent agreement was found between experiment and theory.
