Abstract:
1. An antenna operable to transmit or receive radio frequency signals at a specified frequency and to be used with a device for controlling power delivered to an electrical load, the antenna comprising: a first radiating loop of conductive material having a capacitance and an inductance, the capacitance and the inductance forming a circuit being resonant at the specified frequency, the first radiating loop transmitting and receiving radio frequency signals external to the device for controlling power delivered to the electrical load; and a second feed loop of conductive material having two ends adapted to be electrically coupled to an electronic circuit, the second feed loop being substantially only magnetically coupled to the first radiating loop and electrically insulated from the first radiating loop; said first radiating loop and second feed loop each having a loop axis, the loop axes of the first radiating loop and second feed loop being substantially parallel or coincident said first radiating loop and second feed loop forming a single antenna contained in said device for controlling power delivered to the electrical load.
