Abstract
Described herein are techniques related to near field coupling and wireless power transfers. A portable device may include a coil antenna that includes an upper loop and a lower loop to form a figure-eight arrangement. The figure-eight coil antenna arrangement is wrapped against top and bottom surfaces of a component to establish near field coupling through front side, top side, bottom side, or corner side of the portable device. Further, a flux guide may be placed between the coil antenna and the component to facilitate magnetic flux at the upper loop and the lower loop to induce current of the same phase during receive mode. During transmit mode, the flux guide facilitates the magnetic flux at the upper loop and the lower loop to generate magnetic fields of the same direction.
