1. A wireless charging (WLC) device comprising:
a dynamically reconfigurable transmitter configured to:
wirelessly transmit power as a first type of wireless transmission to a chargeable device through an antenna; and
wirelessly transmit data as a second type of wireless transmission to the chargeable device through the antenna; and
a controller configured to:
dynamically reconfigure an antenna impedance matching configuration of the dynamically reconfigurable transmitter from at least one of a symmetric impedance matching configuration to an asymmetric impedance matching configuration or from the asymmetric impedance matching configuration to the symmetric impedance matching configuration based on at least one of the types of wireless transmission or a wireless transmission efficiency for the type of wireless transmission.
