| 摘要 |
The invention relates to a radar sensor comprising a multi-layer printed circuit board structure (10), an antenna (12), which has a plurality of overlapping electrically conductive layers of the printed circuit board structure, a control circuit (14) for generating a high-frequency signal to be emitted via the antenna (12), and a feed structure (24) for feeding the high frequency signal to the antenna, characterized in that the feed structure (24) is mounted opposite the antenna (12) on a rear face of the printed circuit board structure (10). |
