<p>The present invention relates to an HF UHF multi-band RFID tag antenna capable of using an HF band and a UHF band at the same time. The HF UHF multi-band RFID tag antenna comprises: a UHF tag antenna (10) consisting of a left antenna pole (11), a left meander line (12) connected to the left antenna pole (11), an antenna loop (13) connected to the left meander line (12), a right meander line (14) connected to the antenna loop (13), a right antenna pole (15) connected to the right meander line (14), and a UHF chip (16); and an HF tag antenna (20) consisting of a plurality of planar coil antennas (21) having the shape of a rectangular strip (21a), a jumper (22) formed on the planar coil antenna (21), and an HF chip (23) mounted on the end of the innermost rectangular strip (21a). The HF UHF multi-band RFID tag antenna of the present invention can use an HF (13.56MHz) band and a UHF (920MHz) band at the same time, is a film print type using low-priced conductive ink to enable a double band of the HF band and the UHF band, can provide a long-range (6 to 7 mm) identification tag in the UHF band while operating in the HF band, has a simple structure to reduce costs required for the manufacture of the product, and can be stably used for a long time without failure while having excellent economical efficiency.</p> |
