| 摘要 |
A radar apparatus of the present invention includes an antenna member capable of emitting or receiving microwaves; a feed unit including a plurality of waveguides each having one end connected to a base portion of the antenna member; a radio frequency circuit in contact with the feed unit; an information-processing circuit; a signal line connecting the radio frequency circuit and the information-processing circuit; and a common board equipped with the radio frequency circuit and the information-processing circuit. Since planar positions of the information-processing circuit and the radio frequency circuit on the common board do not overlap with each other, it is possible to downsize the radar apparatus. The common board includes a closed foil made of conductive material and surrounding the radio frequency circuit, and the closed foil made of conductive material is grounded. |
