According to the incident angle domain principle, the design of omnidirectional one-dimensional photonic crystal reflector in ultraviolet region is realized with all-dielectric coating series on quartz glass substrate. Two one-dimensional photonic crystals without omnidirectional reflective band are added in angle domain by using transmission matrix method, it is worked out theoretically that there exists omnidirectional forbidden band for synthesized photon, wavelength rangle of the forbidden band is 328.95～352.11 nm, relative bandwidth is 6.80%. Synthesized photonic crystal is fabricated on quartz glass substrate with two coating materials HfO2 and SiO2 by electron beam vaporization. If transmissivity is below 1%, it is photonic crystal forbidden band, the wavelength range of the forbidden band is 331.2～350.4 nm, the relative bandwidth is 5.63%. The result validates the angle domain addition design.
