Dipole antenna and RFID tag using same

The utility model provides a dipole antenna and an RFID (radio frequency identification) tag using the antenna. The antenna comprises a bent dipole (11) and an induction coil (12), wherein, the bent dipole (11) is electrically connected with the induction coil (12) indirectly or directly in an inductively coupled manner; the bent dipole (11) comprises two parts; the induction coil (12) is arranged between the two parts of the bent dipole (11); and feed points (111 and 112) used for being connected with a chip are arranged on the induction coil (12). The tag comprises the antenna, a substrate and the chip. The dipole antenna has a simple structure, is convenient to manufacture, achieves large gains, has large bandwidth, can conveniently regulate the impedance and the resonant frequency, can adapt to various application environments, and is miniaturized.
