Abstract
The embodiments described herein include a wireless-power-transmitting antenna formed from a stamped piece of metal. One such antenna includes: (i) a signal feed, defined by a single stamped piece of metal, that conducts a signal that controls wireless power transmission and (ii) resonators, each of which is defined by the single stamped piece of metal, that transmits power transmission waves in response to receiving the signal, where each resonator: (a) is planar with respect to a first plane and vertically aligned with each resonator, (b) is coupled to another resonator via curved sections of the stamped piece of metal that are in contact with the signal feed, each curved section extending along a second plane that is orthogonal to the first plane such that respective gaps are formed between each resonator, and (c) receives the signal via a respective curved section of the single stamped piece of metal.
