AI Technical Summary
Existing implantable medical devices suffer from antenna design limitations, biocompatibility issues, and low power transmission efficiency. In particular, the lack of research on circular polarization affects performance and data transmission efficiency in complex in vivo environments.
A miniaturized ultrawideband circularly polarized implantable antenna was designed, employing a dielectric substrate and a cladding layer structure. By etching helical and T-shaped slots on the radiating and ground planes and feeding them with short-circuit probes, combined with the design of an asymmetric U-shaped rectangular slot, miniaturization and wide-bandwidth circular polarization were achieved.
It achieves wide bandwidth (1.75GHz-3.01GHz), circular polarization, and miniaturization in the biological telemetry band, with a small size and low profile, improving power transmission efficiency and resistance to multipath effects.
