In this letter, we present a small implantable antenna for MedRadio (401–406 MHz) and ISM (433–434.8 MHz) bands. The antenna is designed to be implanted under the skin and therefore tested by using skin-mimicking gels. We found very good agreement between the simulated and measured return loss. The antenna provided reliable data telemetry up to 20 m when tested indoors.
