Apple's patent
FIG. 12 illustrates a docking station that includes a reradiating
antenna and an inductive charging circuit for inductively charging a
handheld device. As shown, the dock housing is configured to receive a
handheld device. While the dock housing is shown to receive the handheld
device in an upright position, other dock housing configurations for
receiving the handheld device along its other sides are also possible.
The dock housing is further configured to enable charging the battery of
the handheld device through an inductive charge coupling mechanism, and
to also provide improved wireless communication by integrating the
reradiating antenna as shown. The charge circuit is connected between
the inductive charge coupling mechanism and a port for receiving power.
