A novel S-shaped quad-band planar inverted-F antenna (PIFA) is proposed for implantable biotelemetry in the Medical Device Radiocommunications Service (MedRadio) band (401406MHz), Wireless Medical Telemetry Service (WMTS) band (14271432MHz), and industrial, scientific, and medical (ISM) bands (433-434MHz and 2.42.4835GHz). The proposed antenna reveals compact dimension of 254mm3 (10 10 2.45 mm3) and is composed of three substrates and a superstrate, which are constructed from an S-shaped radiator (layer 1) and two twin radiators of spiral structures (layer 2 and layer 3). The optimal antenna characteristics were measured in the ground pork skin, and the measured bandwidths are 150MHz for the MedRadio and ISM bands (433MHz), 52MHz for the WMTS band, and 102MHz for the ISM band (2.4GHz), respectively. The characteristics of proposed antenna are enough to support the applications of implantable body area networks (BAN) for biotelemetry and can completely cover main available frequency bands of BAN for biotelemetry below 3GHz.
