1. Apparatus comprising:
- a supercapacitor, comprising an electrolyte and a first surface and a second surface, the first surface being opposite the second surface;
a first printed circuit including a first conductor configured to operate as a first antenna, configured at least for wireless communication by transferring data bits wirelessly, positioned adjacent the first surface and configured to function as a current collector for the supercapacitor, and having a first electrical length to resonate in a first operational frequency band;
a second printed circuit including a second conductor configured to operate as a second antenna, positioned adjacent the second surface and configured to function as a current collector for the supercapacitor, the second conductor having a second electrical length to resonate in a second operational frequency band, wherein the supercapacitor is sandwiched between the first printed circuit and the second printed circuit, wherein the first antenna and the second antenna are configured to function simultaneously as antennas and as current collectors for the supercapacitor, wherein the first electrical length and the second electrical length are different and wherein the second conductor is galvanically isolated from the first conductor;
and charging circuitry configured to charge the supercapacitor via the first conductor and the second conductor;
wherein the first operational frequency band and the second operational frequency band are configured to one of partially overlap in frequency and not overlap in frequency.
