Abstract

An antenna array is provided, which may include a connection portion and a plurality of antenna units. The antenna units may be disposed on the two sides of the connection portion respectively. The proximal end of each of the antenna units may be connected to the connection portion and the distal end of one or more of the antenna units may be grounded. The length of each of the antenna units may be less than or equal to 1 / 4 wavelength of the operating frequency of the antenna array, and the distance between any two adjacent antenna units may be less than or equal to 1 / 2 wavelength of the operating frequency of the antenna array.

Description

technical field [0001] The present invention relates to an antenna array, in particular to an antenna array that can effectively improve the viewing angle range. The invention also relates to a vehicle collision avoidance radar comprising such an antenna array. Background technique [0002] Millimeter wave radar has the advantages of small size, light weight and high resolution, and is not easily affected by environmental factors. In addition, compared with lidar, millimeter-wave radar has a price advantage, so it is more widely used. [0003] Millimeter wave radar can provide different information such as distance, angle and speed by identifying the position of objects around the vehicle, and provide this information to the driver to assist the driver in making timely road condition judgments. Millimeter wave radar can be applied to automobile collision avoidance radar and various auxiliary systems, such as forward collision warning (Forward Collision Warning, FCW) system...
