Focused antenna, multi-purpose antenna, and methods related thereto

摘要

Exemplary embodiments are directed to a device including a focused antenna. A device may include a minor plane surface and an antenna positioned proximate the minor plane surface. The antenna may be configured for generating a field focused around the minor plane surface. The antenna may further include an element extending from the minor plane surface toward another minor plane surface of the device.

主权项

1. A device configured to wirelessly receive charging power, comprising:
a coil configured to generate a magnetic field with an intensity level at a center of an upper or a lower first device edge that is greater than an intensity level of the magnetic field at a center of a second device edge, a center of a third device edge and a center of a fourth device edge, the coil being further configured to wirelessly communicate with an external device substantially through the first device edge using the magnetic field at the first device edge, the coil centered around a first axis; a loop antenna electrically connected to the coil and centered around a second axis different than the first axis, the loop antenna configured to wirelessly receive charging power via a wireless field, a portion of the loop antenna at least partially enclosing the coil; and a battery electrically connected to and configured to be charged with charging power received from the loop antenna.
