Abstract
Exemplary embodiments are directed to wireless power transfer to an electronic circuit including a wireless charging receive antenna comprising a first loop of an energy receiving conductor and at least another loop of said energy receiving conductor electrically coupled to the first loop. The loops form a multi-turn loop antenna to resonate at a wireless charging frequency and provide wirelessly received power to the electronic device. The multi-turn loop antenna is configured for affixing to a housing of the wireless device.
