A short-range wireless power transmission scheme is used between two movably or detachably coupled device parts in an electronic device. In a device, such as a foldable or slidable mobile phone, both device parts have some electronic components that require electronic power but only one part has a power source. For example, a phone cover has a display but there is no power source in the phone cover. A receiver can be implemented in the cover to receive microwaves from a transmitter in the phone body. The receiver and the transmitter can be arranged such that, the antennas are placed as close to each other as possible in order to achieve best efficiency of energy and data transfer. If one pair of antenna is not enough, multiple antennas or antenna arrays can be used for this purpose. Different antenna pairs can be configurable for different purposes.
