Abstract
An antenna fabrication method includes depositing a conductive material on a surface of a double injection mold that includes a first surface portion comprising a primary material corresponding to a slot of the antenna and a second surface portion comprising an overmold material corresponding to a conductive surface of the antenna such that conductive material does not deposit on the primary material while it deposits on the secondary material, thereby resulting in multiple loops of the conductive material on the surface of the double injection mold, and providing two contact points to the conductive material, the contact points being separated from each other by a gap in the conductive material.
Claims20
A method of fabricating an antenna, comprising:
- inserting a slot in a single material injection mold with a plating-resistant material such that that a conductive material does not deposit on the slot;
- depositing, after the inserting, a conductive material on a surface of the single material injection mold such that the slot corresponds to a non-conductive surface of the antenna, thereby resulting in multiple loops of the conductive material;
- and
- providing two contact points to the conductive material, the contact points being separated from each other by a gap in the conductive material.

- and
- providing two contact points to the conductive material, the contact points being separated from each other by a gap in the conductive material.
A wireless power system, comprising:
- a wireless charging transmitter device including a power source electrically coupled to an array of three-dimensional (3D) antennas, wherein each 3D antenna includes a conductive material having multiple windings, wherein the multiple windings are electrically separated from each other by a single continuous slot, wherein the array is arranged such that at least two 3D antennas are acute or perpendicular to each other, and wherein each 3D antenna comprises multiple windings of:
- at least one of (1) a conductive material deposited on a surface of a single-material injection mold having a slot running along a length of the single-material injection mold, the slot positioned to provide electrical isolation to the multiple loops of conductive surface that are formed by deposition of conductive material on the single-material injection mold or (2) a conductive material deposited on a surface of a double injection mold to form a first surface portion comprising a primary material corresponding to the slot and a second surface portion comprising an overmold material corresponding to a conductive portion of the coil.
