Summary: | Techniques for wireless transmitting power are described. An example power transmitting unit includes a magnetic resonance-type transmit coil array comprising a plurality of coil elements, wherein each coil element is tuned to a same resonant frequency. The power transmitting unit also includes a power generating circuitry to deliver current to the transmit coil array to wirelessly power a device within an active wireless charging area of at least one of the plurality of coil elements. Each coil element exhibits a plurality of zero point distances and the spacing between neighboring coil elements corresponds with the plurality of zero point distances. |
