Abstract
A planar inductive resonant coupler comprising a circular planar loop antenna; and an element disposed within and co-planar with a loop formed by the antenna; wherein one or more antenna or element dimensions are sized to tune a coupler resonance of the coupler. A method of locating a subcutaneous planar inductive resonant coupler including: providing the subcutaneous planar inductive resonant coupler; providing a locating device configured to couple with the subcutaneous planar inductive resonant coupler; placing the locating device within a coupling range of the subcutaneous planar inductive resonant coupler; plotting a location for each of one or more resonant frequencies of the locating device with respect to a surface under which the subcutaneous planar inductive resonant coupler is expected to be located; and identifying a location for a specific resonant frequency of the subcutaneous planar inductive resonant coupler on the surface.
