AN ANTENNA FOR RADIO FREQUENCY IDENTIFICATION SYSTEMS, METHODS OF CONFIGURING SAME, AND A RADIO FREQUENCY IDENTIFICATION READER

摘要

The present invention provides an antenna for an RFID system, including a conductor line (8), wherein the conductor line includes at least two loop parts (80, 82) and at least one connecting part (81). Successive loop parts (80,82) are connected by a connecting part (81). The connecting part is disposed in such a manner as to be separated from said loop. Although the loop circumference is in the order of a wavelength the connecting part (81) ensures the current on the loop parts (80, 82) to flow in the same diretion. Thus, the antenna can attain a sufficient size in a UHF RFID system and satisfy the reading distance requirement for a near-field UHF RFID reader. Alternative solutions for the connecting part are detour lines and phase shifting devices.
