Abstract
A device for collecting energy has first, second, and third capacitive plates, each spaced from, substantially parallel to, and electromagnetically coupled to each other. An inductor is coupled between two of the plates, and a load resistance is inductively coupled to the inductor for drawing energy from electromagnetic field excitation between the plates. In a further embodiment, the inductor includes a first inductor coupled in series with a second inductor, and the load resistance is inductively coupled to the second inductor for drawing energy from electromagnetic field excitation between the plates, and the device further includes a first capacitor coupled in parallel with and spaced apart from the first inductor, and a second capacitor coupled between the first and second capacitive plates. In a still further embodiment, energy is collected by a coaxial transmission feed line.
