Abstract

The invention discloses a vehicle-mounted MIMO radar antenna layout structure which is applied to a radio frequency chip. The layout structure comprises a first transmitting antenna group which comprises a plurality of first transmitting antennas extending and arranged along a first direction, a second transmitting antenna group which comprises a plurality of second transmitting antennas which extend and are arranged along the first direction, and a first receiving antenna group which comprises a plurality of first receiving antennas which extend and are arranged along the first direction, wherein the second transmitting antenna group is located between the first transmitting antenna group and the first receiving antenna group in a second direction, and the second direction is perpendicular to the first direction. According to the invention, the axisymmetric structure is utilized, the distance from the antenna at the farthest end of the radio frequency chip to the radio frequency chippin is the shortest, and the minimum feeder loss is realized; and long-distance transmitting antennas and short-distance transmitting antennas extend along different transverse lines, so that the problem of layout interference caused by the problem of antenna spacing between the antennas can be avoided.

Description

technical field [0001] The invention relates to the field of vehicle-mounted electronic products, in particular to a vehicle-mounted MIMO radar antenna layout structure. Background technique [0002] Due to the continuous improvement of automobile safety standards in various countries, the active safety technology Advanced Driver Assistance System (ADAS) has shown a rapid development trend in recent years. Automotive millimeter-wave radar has been recognized by automotive electronics manufacturers for its advantages of all-weather work, high precision, strong anti-interference ability, strong penetrating ability, long detection distance, speed of action over 120 kilometers per hour, and no effect on the overall appearance of the vehicle. Mainstream choice, with huge market demand. [0003] In order to achieve higher angular resolution, increasing the antenna aperture is the most direct technical choice. MIMO technology can increase the antenna aperture on the premise of in...
