1. A wireless-power-receiving device comprising:
a flexible housing of a case with (i) a planar surface and (ii) four sidewalls extending perpendicularly from the planar surface, wherein:
the planar surface and the four sidewalls define an open space that is sized to receive a housing of an electronic device, and
the electronic device, when received by the flexible housing of the case, is in contact with respective inner surfaces of each of the four sidewalls;
an antenna array that is directly coupled with at least one sidewall of the four sidewalls and that is not directly coupled with the planar surface, the antenna array (i) being configured to harvest radio frequency (RF) wireless energy transmitted by a wireless-power-transmitting device and (ii) including a plurality of receive-only antennas, wherein a number of receive-only antennas in the plurality of receive-only antennas is selected based on a size of the electronic device; and
rectifying circuitry configured to (i) convert the RF wireless energy harvested by the antenna array into useable power and (ii) provide the useable power to the electronic device.
