AI Technical Summary
Technical Problem
Existing medical implant systems face challenges in maintaining consistent and strong wireless communication links without the use of magnets, which are prone to misalignments and movements, leading to variable power transfer efficiencies.
Method used
The implementation of a multi-coil array configuration for magnetic induction antennas, where each coil is in series electrical connection and positioned to have zero mutual inductive coupling, allowing for a larger communication area and improved coupling stability despite misalignments.
Benefits of technology
This configuration enhances power transfer efficiency by up to 30% over a wide range of misalignments and movements, providing a more reliable and consistent wireless communication link for medical implants.

Abstract
An apparatus includes at least a first MI antenna and a second MI antenna. The first MI antenna includes an electrically conductive and substantially planar first coil extending around and substantially orthogonal to a first antenna axis. The second MI antenna includes an electrically conductive and substantially planar second coil extending around and substantially orthogonal to a second antenna axis. The second antenna axis is substantially parallel to the first antenna axis. The second coil in series electrical connection with the first coil. The first and second MI antennas have a mutual coupling coefficient that is substantially
