Disclosed is a wireless power transmitter for wirelessly delivering power to a receiver device, the wireless power transmitter including: a plurality of unit cells configured to radiate one or more radio frequency (RF) power transmission waves, each unit cell in the plurality of unit cells including: (i) a metal portion having an interior perimeter that surrounds an aperture defined by the metal portion; and (ii) an antenna that is aligned with the aperture in a first dimension, the antenna being configured to radiate one or more RF power transmission waves for wirelessly charging a receiver device. The one or more RF power transmission waves leak from the wireless power transmitter at least in part through the aperture when the receiver device is positioned within a threshold distance from the unit cell.

A system for mounting a wireless cellphone charger to a cellphone, including a cellphone case and a wireless cellphone charger mount. The cellphone case defines a bore and a recess disposed adjacent the bore and includes a shell and a first retention ring having a first metal plate receivable by the recess to secure the first retention ring to the shell. The wireless cellphone charger mount has a wireless cellphone charger, a second metal plate and an interface comprising a protrusion receivable by the bore. The wireless cellphone charger is securable to the cellphone case when the first retention ring is secured to the shell by aligning the protrusion and the bore and magnetically coupling the first and second metal plates.
