A compact-implantable-antenna-based biosensor is presented for the Medical Device Radiocommunications Service (MedRadio) (401–406, 413–419, 426–432, 438–444, and 451–457 MHz), long term evolution (LTE) 700 (698–787 MHz), global system for mobile communications (GSM) 850 (824–894 MHz), GSM900 (880–960 MHz), and Wireless Medical Telemetry Service (WMTS) (1395–1400 MHz) band applications. The proposed antenna has a wide operating bandwidth and small size owing to the effective use of meandering strips on the radiator and ground plane. An optimal antenna biosensor with compact dimensions of 15 × 15 × 2.25 mm3 is fabricated and measured in a skin-mimicking gel. The measured 10 dB return loss bandwidth ranged from 376 to 1411 MHz, effectively covering the MedRadio, LTE700, GSM850, GSM900, and WMTS bands. Furthermore, the measured return loss exhibited stable characteristics with varying temperatures of the contact tissue, making it suitable for implanted biotelemetry and other wireless telemetry applications.
