Abstract
Official abstract text for this publication.
One aspect provides a wireless power transmitter. The wireless power transmitter includes a transmit antenna configured to generate a field for wireless transmit power in both a first and second configuration. The wireless power transmitter further includes a first capacitor. The wireless power transmitter further includes at least one switch configured to selectively connect the first capacitor in one of the first and second configuration. The first capacitor can be in series with the transmit antenna in the first configuration and in parallel with the transmit antenna in the second configuration.
