The invention provides an anti-rolling passive ultrahigh frequency radio frequency identification tag and a vehicle positioning system. The anti-rolling passive ultrahigh frequency radio frequency identification tag comprises an electronic tag board 3; the electronic tag board 3 comprises a microstrip patch antenna 31, a microstrip feeder 32, a feed through hole 33, a tag chip 35 and a circuit dielectric board 37; the microstrip patch antenna 31 is arranged on the upper side of the circuit dielectric plate 37, and the tag chip 35 is arranged on the lower side of the circuit dielectric plate 37; the feed through hole 33 is formed in the circuit dielectric plate 37 and is communicated with the upper side and the lower side of the circuit dielectric plate 37, and the microstrip feeder 32 penetrates through the circuit dielectric plate 37 and is connected with the microstrip patch antenna 31 and the tag chip 35 respectively. The antenna part is arranged on the upper side of the circuit dielectric plate, and the feed part is arranged on the lower side of the circuit dielectric plate, so the stress area of the feed structure can be effectively reduced through the separated design, and the purpose of rolling resistance is achieved.
