EMI Mitigation Features In Wireless Power Transmission Systems

An antenna for a wireless power transmission system includes a coil layer and a filter layer. The coil layer includes turns, a first coil end, and a second coil end. The coil layer is electrically connected to a power conditioning system via a positive electrical node connected to the first coil end and a negative electrical node connected to the second coil end. The filter layer is positioned in a stack-up with the coil layer and includes tines each comprising a conductive material, positioned proximate to the plurality of turns, and terminating at one end. The filter layer includes a filter end that is electrically connected to a ground of the wireless transmission system, wherein the filter layer is configured to absorb an E-field emitted by the coil layer and route the absorbed E-field to the ground.
