A gas radiant cooktop comprises: a housing, the upper side of which is open and has a predetermined internal space; Ceramic glass covers the upper end of the shell and is combined with the material to be cooked. The burner shell is combined with the lower surface of ceramic glass to form an exhaust passage with the lower surface of ceramic glass, and is combined with multiple dual-structure burners. A radiation burner, combined with the side of the burner shell, produces a radiation wave when burning the mixture gas; The common exhaust unit extends to the rear surface of the housing, so that when the exhaust unit is located between multiple radiation burners and is combined with each exhaust channel formed, the exhaust unit is generated by multiple radiation burners separately at the side of the burner housing and the gas is discharged to the exhaust pipe at the rear of the housing.
