Description
Zhiwei Song and co-authors design a scalp-implanted antenna for medical telemetry in a 2024 paper. Implants that report brain or body data need small antennas that work inside the head at the standard medical band near 2.45 gigahertz. Their design packs two antenna elements into a tiny footprint, with the pair sending in opposite circular polarization senses for signal diversity.
Slots cut into the patch and ground plane give very wide bandwidth and the circular polarization the design needs. Tests used layered and real human head models plus minced pork as tissue stand-in. The antenna reached good isolation between its two elements and a strong link margin, and absorption safety measures were checked. Performance held up across the test setups.
