1. A wireless power transmission antenna comprising:
- a printed circuit board (PCB) including a first transmission line that conducts a first power transmission signal;
a dielectric resonator that is;
mechanically coupled to the PCB, andconfigured to radiate the first power transmission signal;
a first feed element that is;
electronically coupled to the first transmission line and to the dielectric resonator, andconfigured to (i) receive the power transmission signal via the first transmission line and (ii) excite the dielectric resonator with the first power transmission signal; and
a plurality of patches, wherein;
each respective patch of the plurality of patches is electronically coupled to a respective via of a plurality of vias, the respective via passing through the PCB to couple the respective patch with a ground plane that is coupled to the first transmission line of the PCB; and
the first feed element is the plurality of patches.

Abstract
A wireless power transmission antenna includes a printed circuit board (PCB) with a first transmission line that conducts a first power transmission signal. A dielectric resonator that is mechanically coupled to the PCB is configured to radiate the first power transmission signal. A first feed element that is electronically coupled to the first transmission line and to the dielectric resonator is configured to receive the power transmission signal via the first transmission line and excite the dielectric resonator with the first power transmission signal.
