发明名称 Antenna
摘要 An antenna comprises a conductive helix (10) positioned parallel to a ground plane (12). One end (14) of the helix is coupled to the ground plane (12), while the other end (16) is left open. Radio frequency signals (20) are fed (18) into the open end of the helix to excite the antenna and radiate the radio frequency signal.
