Abstract:
An apparatus comprising first and second circuit boards, and an antenna for transmitting and/or receiving electromagnetic signals, the first and second circuit boards each comprising an electrically conductive layer, and a capacitive element configured to be charged and discharged, the apparatus configured such that a chamber is defined between the first and second circuit boards with the capacitive elements contained therein and facing one another, the chamber containing an electrolyte, wherein the electrically conductive layer of the first circuit board is configured to serve as a reference ground for the antenna, and wherein discharge of the capacitive elements is configured to provide a flow of current to an amplifier configured to drive the antenna.
Abstract:
Apparatus comprising: an electric double layer capacitor having a first surface and a second surface, the first surface being opposite the second surface; a first conductor positioned adjacent the first surface and configured to function as a current collector for the electric double layer capacitor, and having a first electrical length to resonate in a first operational frequency band; and a second conductor positioned adjacent the second surface and configured to function as a current collector for the electric double layer capacitor.
