Helix antenna

Abstract:

A communications system such as a global position system (GPS) device, a spacecraft tracking device, a handheld radio, or any other communications device may include one or more helix antennas. Each helix antenna may include a conductive circular ring at a distal end of one or more helical arms. In a helical antenna with multiple arms, the arms may be shorted together at the distal end by the conductive circular ring.
