Stamped three-dimensional antenna
First Claim
1. A wireless-power-transmitting antenna formed from a stamped piece of metal comprising:
- at least one signal feed, which is defined by a single stamped piece of metal, that conducts at least one signal that controls wireless power transmission in the antenna; and
a plurality of resonators, each of which is defined by the single stamped piece of metal, that transmits power transmission waves in response to receiving the at least one signal from the signal feed, wherein each resonator of the plurality of resonators;
is planar with respect to a first plane and is also vertically aligned with each other resonator of the plurality of resonators;
is coupled to another resonator of the plurality of resonators via respective curved sections of the single stamped piece of metal that are each in contact with the at least one signal feed, each respective curved section extending along a second plane that is orthogonal to the first plane, such that respective gaps are formed between each of the plurality of resonators; and
receives the at least one signal via a respective curved section of the single stamped piece of metal,further wherein the power transmission waves transfer energy that is used by a wireless power receiver to power or charge an electronic device.

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.
