Abstract: A polygonal helix antenna for an RFID reader is provided to adjust a reflective loss characteristic and an operational frequency of a wide band by adjusting an electrical length according to a frequency in a limited antenna size. A polygonal helix antenna for an RFID reader includes a path section. The path section is matched with a feeding line(11), and is operated as an antenna of a predetermined frequency band. The path section forms a polygonal shape when the path section is viewed from a radiation plane in parallel with a ground plane(14). The antenna section has at least one bent shape to the ground plane or a vertical direction. The antenna section comprises a single antenna path of a polygonal shape when the antenna section is viewed from the radiation plane.
