Abstract: Novel and advantageous systems and methods for wireless power transfer (WPT) via multiple-resonator conformal strongly coupledmagnetic resonance (CSCMR) are provided. Instead of using a single loop as a resonator, multiple resonators can be used. This leads to lower operating frequency (e.g., 30% decrease), extended WPT range (e.g., 20% increase), and higher WPT efficiency compared to single-resonator systems of the same size.

Abstract: Novel and advantageous antennas are provided. A multi-functional antenna can morph in order to change geometrical shape and thereby change its antenna radiation characteristics. Such characteristics can include radiation pattern, bandwidth, beamwidth, operational frequency, and directivity. The antenna can therefore be multifunctional such that one single antenna can serve multiple applications.

A planar resonant source element is coplanar with the planar source conductor and has a first resonant frequency. The planar resonant source element has a Q factor that is at a maximum at the first resonant frequency. A planar resonant load element resonates at the first resonant frequency. A planar load conductor is electromagnetically coupled to and coplanar with the planar resonant load element and generates a current in response to the second periodically fluctuating electromagnetic near field from the planar resonant load element.
