A Compact Broadband Antenna with Dual-Resonance for Implantable Devices

Blog Article

A compact broadband implantable patch antenna is designed for the field of biotelemetry and experimentally demonstrated using the Medical Device Radiocommunications Service (MedRadio) band (401–406 MHz).The proposed antenna can obtain a broad impedance bandwidth COSMETICS by exciting dual-resonant frequencies, and has a compact structure using bent metal radiating strips and a short strategy.The total volume Cooker of the proposed antenna, including substrate and superstrate, is about 479 mm3 (23 × 16.4 × 1.27 mm3).

The measured bandwidth is 52 MHz (382–434 MHz) at a return loss of −10 dB.The resonance, radiation and specific absorption rate (SAR) performance of the antenna are examined and characterized.
