Abstract EN
Minimally invasive approach to intracranial pressure monitoring is desired for long-term diagnostics.
The monitored pressure is transmitted outside the skull through an implant antenna.
We present a new miniature (6 mm × 5 mm) coplanar implant antenna and its integration on a sensor platform to establish a far-field data link for the sensor readout at distances of 0.5 to 1 meter.
The implant antenna was developed using full-wave electromagnetic simulator and measured in a liquid phantom mimicking the dielectric properties of the human head.
It achieved impedance reflection coefficient better than −10 dB from 2.38 GHz to 2.54 GHz which covers the targeted industrial, scientific, and medical band.
Experiments resulted in an acceptable peak gain of approximately −23 dBi.
The implant antenna was submerged in the liquid phantom and interfaced to a 0.5 mW voltage controlled oscillator.
To verify the implant antenna performance as a part of the ICP monitoring system, we recorded the radiated signal strength using a spectrum analyzer.
Using a half-wavelength dipole as the receiving antenna, we captured approximately −58.7 dBm signal at a distance of 1 m from the implant antenna which is well above for the reader with sensitivity of −80 dBm.
