Abstract
The present invention relates to a RFID tag antenna with ultra-thin dual-frequency micro strip patch antenna array, the RFID tag antenna comprises an units array (), a substrate () and a substrate base plate (); the radiation units array () is configured to be asymmetrically distributed around a chip; a first radiation unit () and a third radiation unit () form a low-frequency resonant system of the RFID tag antenna (), and a second radiation unit () and a fourth radiation unit () form a high-frequency resonant system of the RFID tag antenna (), thereby achieving a dual-frequency effect, and enabling the RFID tag antenna of the present disclosure to be compatible with both of the working frequency bands in Europe and in U.S., and thus achieving a dual-frequency-band property.
