PROBLEM TO BE SOLVED: To provide a radar device which can be reduced in size.SOLUTION: The radar device comprises: an antenna member capable of emitting or receiving microwaves; a feed part having a plurality of wave guides connected to the proximal ends of the antenna member at one ends thereof, respectively; a high-frequency circuit part being contact with the feed part; an information processing circuit part; a signal line which connects the high-frequency circuit part and the information processing circuit part; and a common substrate which has the high-frequency circuit part and the information processing circuit part mounted thereon. On the common substrate, plane positions of the high-frequency circuit part and the information processing circuit part do not overlap, the common substrate has closed conductive foil surrounding the high-frequency circuit part, and the closed conductive foil is grounded.SELECTED DRAWING: Figure 2 |
