    Abstract: Described herein are techniques related to near field coupling and wireless power transfers. A device may include a cascaded coil antenna to include a first coil antenna that is connected in series with a second coil antenna. The first and second coil antennas are independent antennas prior to cascading and are located in different surfaces of the device to establish near field coupling through front side, top side, bottom side, or corner side of the portable device. Furthermore, a flux guide may be placed in the cascaded coil antenna to facilitate magnetic flux at the first coil antenna and the second coil antenna to induce current of the same phase during receive mode. During transmit mode, the flux guide facilitates the magnetic flux at the first coil antenna and the second coil antenna to generate magnetic fields of the same direction.

    Abstract: Techniques for focusing the energy radiated by a wireless power transmitting unit are described. An example power transmitting unit includes a transmit coil configured to generate a magnetic field to wirelessly power a device within an active wireless charging area. The power transmitting unit also includes a power generating circuitry to deliver current to the transmit coil to generate the magnetic field. The power transmitting unit also includes a patch array disposed in parallel with the transmit coil to reduce the strength of the magnetic field at frequencies outside of the operating frequency during operation of the power transmitting unit.
