| 摘要 |
The present invention relates to an RFID tag aerial with an ultra-thin dual-frequency microstrip patch aerial array, the RFID tag aerial comprising an element array (1), a substrate (2) and a substrate base plate (3); the radiating element array (1) is asymmetrically distributed around a chip; a first radiating element (5) and a third radiating element (7) form the low-frequency resonant system of the RFID tag aerial (9); and a second radiating element (6) and a fourth radiating element (8) form the high-frequency resonant system of the RFID tag aerial (9), thus achieving a dual-frequency effect, and enabling the RFID tag aerial of the present invention to be compatible with both European and American frequency ranges, therefore achieving a dual-frequency-range effect. |
