1. A planar inductive resonant coupler comprising:
a circular planar loop resonator comprising a single loop; and
a circular metal pad element disposed within and coplanar with the circular planar loop resonator;
wherein one or more circular planar loop resonator dimensions or circular metal pad element dimensions are sized to tune a coupler resonance of the coupler by forming a gap with a selected equidistant gap width between a circumference of the circular metal pad element and an inner circumference of the circular planar loop resonator; and
wherein the circular planar loop resonator and the circular metal pad element disposed within and coplanar to the circular planar loop resonator are configured to establish electric fields across the gap and are configured to be coupled to circuitry, to receive or to transmit electromagnetic energy to or from a surrounding environment, and to transmit the electromagnetic energy to the circuitry.
