Abstract

The invention discloses a biomedical telemetering implantable high-gain antenna based on a near-zero refractive index metamaterial, and belongs to the technical field of biomedical telemetering implantable antennas. The antenna comprises an antenna radiation unit, a lower-layer dielectric substrate, a metal floor, a metamaterial structure, a coaxial joint, two short-circuit pins and an upper-layer dielectric substrate. The antenna provided by the invention overcomes the disadvantage of low gain of a common implantable antenna, and can keep other indexes of the biomedical telemetering implantable antenna technology unchanged basically. The antenna works at the frequency band of 2.45 GHz (ISM), has the advantages of miniaturization, low profile, high gain, biocompatibility and the like, and is provided to solve the problem of relatively low gain of the conventional implantable antenna.

Description

technical field [0001] The invention belongs to the technical field of biomedical telemetry implantable antennas, in particular to a biomedical telemetry implantable high-gain antenna based on near-zero refractive index metamaterials. Background technique [0002] Today, China has entered an aging society, and the demand for high-quality healthcare services is increasing. Wireless biomedicine has become the main trend of current and future medical development due to its convenience. Wireless biomedical devices have played an important role in health monitoring, medical diagnosis, disease treatment and repair, etc., replacing the discomfort caused by wired connections with human implants, and can obtain beneficial information for diagnosis and follow-up treatment . Implantable antennas are essential to establish a wireless link between implanted devices and external devices, and in vivo communication offers several advantages, including telemetry, access to appropriate medic...
