Abstract
Complementary to an already proposed antenna concept for millimeter-wave automotive radar sensors the design of a planar Yagi-Uda antenna array has been presented. The radar antenna concept consists of end-fire antennas (or arrays) and a cylindrical parabolic reflector that can directly be integrated into the sensor's metal housing. The proposed assembly reduces the antenna substrate area while maintaining a small installation depth. The achieved gain of 16 dBi can be increased up to 22 dBi for the 4-element array by an improved power-divider network and even higher if more antenna elements are used.Keywords
