1. A wireless-power-transmitting antenna comprising:

  • a signal feed configured to conduct a signal that causes the antenna to transmit electromagnetic (EM) power transmission waves; and

    a unitary resonator formed from a single piece of metal, the unitary resonator including a plurality of planar segments interconnected by respective sections,wherein the plurality of planar segments includes;

    (i) a first planar segment positioned on a first horizontal plane;

    (ii) a second planar segment, adjacent to the first planar segment, positioned on a second horizontal plane vertically offset from the first horizontal plane by a first respective section interconnecting the first and second planar segments; and

    (iii) a third planar segment, adjacent to the second planar segment, positioned on a third horizontal plane vertically offset from the second horizontal plane by a second respective section interconnecting the second and third planar segments, andfurther wherein the signal feed directly contacts at least two planar segments of the plurality of planar segments.
