Zusammenfassung:	The utility model provides an antenna device and a radar device, wherein the antenna device is smaller than a traditional antenna, and the antenna device and the radar device can reduce load of a machine. A tube shaft direction of a waveguide tube 12 used for feed is deviated to an X direction, and a connection position between the waveguide tube 12 and a fixing station 14 is more deviated to the right side compared with a connection position between the waveguide tube 12 and a slit waveguide tube 11. Because the connection position between the waveguide tube 12 and the fixing station is deviated by X1 towards the right side direction, so a rotation center position of the antenna device 1 is close to a center of gravity position of the antenna device. If the embodiment of the utility model presents the structure of the antenna device 1, and the waveguide tube 12 used for feed is arranged at the rear of the structure, then on the one hand, height of the antenna device is reduced, and on the other hand, mechani
