摘要

The development of compact biomedical antennas has advanced significantly to meet the increasing demand for efficient and safe implantable devices. This research introduces a small dual-band bio-implantable patch antenna fit for the Medical Implant Communication Service (MICS, 0.403 GHz) along with the Industrial, Scientific, and Medical (ISM, 2.45 GHz) bands. The antenna utilizes a meander-line radiating patch, defective ground structure, and RO3010 superstrate for miniaturization as well as bandwidth enhancement. The produced prototype with 6.2 × 5.2 × 0.5 mm³ dimensions shows dual-band operation with bandwidths of 0.24 GHz (MICS) and 0.73 GHz (ISM) respectively. The simulated gains of -16.73 dB and − 11.16 dB make it possible to have communication that is low-power, safe, and in-body. SAR analysis confirms compliance with IEEE C95.1 standards when normalized to realistic implant power levels. The antenna’s compactness, dual-band performance, and biotelemetry suitability make it a strong candidate for implantable medical devices.
