ABSTRACT:
An antenna operable to transmit or receive radio frequency signals at a specified frequency, the antenna comprising a first printed circuit board comprising a first loop of conductive material having a capacitance and an inductance, the capacitance and the inductance forming a circuit being resonant at the specified frequency; and a second printed circuit board comprising a second loop of conductive material having two ends adapted to be electrically coupled to an electronic circuit, the second loop being substantially only magnetically coupled to the first loop and electrically insulated from the first loop; the antenna for use with a device for controlling the power delivered to an electrical load, further wherein the first loop of the conductive material comprises a break and the capacitance includes a capacitor bridging the break; wherein the first loop comprises a first metal layer on a first side of the first printed circuit board and a second metal layer on a second, opposite side of the first printed circuit board, the first and second layers being electrically connected to each other and wherein the break is provided in one of layers.
