Abstract: A miniaturized Radio Frequency Identification (RFID) tag and a microstrip patch antenna thereof are provided. The miniaturized RFID tag includes: a chip, substrate and a microstrip patch antenna. The microstrip patch antenna is attached to a surface of the substrate and includes a power supply part and a radiation part connected with each other. The power supply part is connected with the chip through a microstrip line. Two sides of the radiation part are provided with at least one slit which has the length of one-half wavelength and enables the tag product to be used normally within a range of shorter than one-half normal wavelength. A maximum point and a minimum point are generated in the radiation part simultaneously, so the tag can be used normally without influencing the performance, even when the tag is in contact with any metal surface. The tag can be miniaturized at the same time.
