Apparatus and associated methods relate to providing wireless power transfer and wireless communications between two electronic components, each having an inductive coil and a microwave antenna centered about a common central axis, thereby ensuring alignment with one another. Wireless power transfer can be performed using electromagnetic coupling between the inductive coils and/or the microwave antennae of the two electronic components. In some embodiments, the two electronic components are an implantable biomedical device and an external interface system for the implantable biomedical device. Power-receive and power-transmit controllers control operation of power transmission by the external interface system and power reception by the implantable biomedical device, respectively. In some embodiments, the microwave antenna has a resonance frequency that is configured by location of an electrical connection to a ground plane. A communication controller can be configured to control the resonance frequency of the microwave antenna by controlling a switch network.

Wireless power transfer and wireless communications between two electronic components

A dielectric substrate made from sunflower seed shells has good moldabiltiy and low water adsorption for use in creating antenna or other devices. The dielectric substrate is made by pyrolizing sunflower seed shells or husks and collecting the resulting tar to create the substrate.
