The phase shifter having excellent magnitude balanced degree and operation bandwidth can be widely used in substrate integrated waveguide devices and systems having special demands to the phase such as beam-forming network, difference circuit, recoverable antenna array, thereby realizing integrated design; the phase shifter is in planar circuit structure; a upper layer metallic copper surface (1) and a lower layer metallic copper surface (2) are respectively located at two sides of the medium substrate (3); two rows of metallic through holes (4) penetrate the medium substrate (3) to connect with the upper layer metallic copper surface (1) and the lower layer metallic copper surface (2), thereby forming a substrate integrated waveguide branch circuit one (5); the other two rows of metallic through holes (4) penetrate the medium substrate (3) to connect with the upper layer metallic copper surface (1) and the lower layer metallic copper surface (2), thereby forming a substrate integrated waveguide branch circui
