An ultra-high frequency radio frequency identification microstrip comprises a medium substrate (1); a conductor (2) formed on a surface of the medium substrate (1); and a metal ground (3) formed on another surface of the medium substrate (1). The conductor (2) comprises a meandering portion (21), and a pair of connection portions (22, 23) located at two ends of the meandering portion (21) and integrally formed therewith, wherein one connection portion (22) is connected to a matched load, and the other connection portion (23) is connected to a feed point. The ultra-high frequency radio frequency identification microstrip has a meandering structure employing spatial coupling of currents in adjacent microstrips and the discontinuity of bent portions, so as to form a strong magnetic field at a position close to and above the ultra-high frequency radio frequency identification microstrip. The length of the ultra-high frequency radio frequency identification microstrip is adjustable and easy to use. A user can select, according to actual requirements, an ultra-high frequency radio frequency identification microstrip having an appropriate meandering period, or connect a random number of ultra-high frequency radio frequency identification microstrips in series according to actual requirements.
