description The invention discloses a differential end-fire antenna based on an SIW structure. The differential end-fire antenna comprises a dielectric substrate, and an SIW transmission line, a skewed slot antenna and a differential feed module which are printed on the dielectric substrate, wherein the SIW transmission line is provided with a short-circuit end and an open-circuit end, and the skewed slot antenna is connected with the open-circuit end of the SIW transmission line to form an SIW-based end-fire antenna; and the differential feed module is used for carrying out differential feed on the SIW-based end-fire antenna. The skewed slot antenna comprises two right trapezoid metal surfaces. And four rectangular gaps are formed in each right-angled trapezoidal metal surface. And the SIW transmission line comprises three rows of U-shaped metal through holes formed in the dielectric substrate A. The differential feed module comprises two feed microstrip lines and a probe. According to the invention, the feed mode is co
