Embodiment Construction

[0021] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein.

[0022] figure 1 A schematic structural diagram of an antenna system provided by an embodiment of the present invention is shown, and the antenna system can be applied to a vehicle-mounted millimeter-wave radar. Such as figure 1 As shown, the antenna system includes an antenna array 10 and a first ground layer 20 and a second ground layer 30 of the antenna array. The first ground layer 20 and the second ground layer 30 are generally metal ground layers. The antenna array 10 is used to radiate electromagnetic waves to free space. The first PCB surface where the first ground layer 20 is located is provided with a plurality...

Abstract

The embodiment of the invention relates to the technical field of antennas, and discloses an antenna system and a vehicle-mounted millimeter wave radar. The system comprises an antenna array and a first grounding layer and a second grounding layer of the antenna array, the antenna array is used for radiating electromagnetic waves to a free space, and a plurality of metal patches are arranged on a first PCB surface where the first grounding layer is located at intervals. The metal patches are used for adjusting the phase of a reflected electromagnetic wave formed after the electromagnetic wave is reflected. According to the embodiment of the invention, the wide-angle sensing capability of the antenna system is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of antennas, and in particular to an antenna system and a vehicle-mounted millimeter-wave radar. Background technique [0002] With the continuous development of intelligent driving technology, vehicle-mounted millimeter-wave radar has been widely used. Vehicle-mounted millimeter-wave radar is a detection radar that works in the millimeter-wave band, and detects obstacles around the vehicle through the antenna system. [0003] In the related art, the antenna system of the millimeter-wave radar generally includes an antenna array and a metal ground, and the antenna array can radiate high-frequency radar signals to free space. However, the inventor found in the process of implementing the embodiments of the present invention that: the high-frequency radar signal radiated by the antenna array will generate a reflected radar signal after passing through the metal ground, and there will be ...
