Radar device for use in corner region of car, has printed circuit boards including respective planar surfaces, where normal vectors to planar surfaces of printed circuit boards point in different directions

摘要

The device has printed circuit boards (1-3) including a transmission circuit section (4) intended to generate and transmit radar signals, and a receiving circuit section (5) intended to receive and recycle the radar signals. Each of the printed circuit boards includes a planar surface, where normal vectors to the planar surfaces of the printed circuit boards point in different directions. The normal vectors are located with respect to each other at an angle greater than or equal to 5 degrees, where the printed circuit boards are mechanically connected.
