Embodiment 1

[0037] Such as figure 1 Shown is a schematic diagram of the structure of the microstrip array antenna system based on 77GHz millimeter wave radar in this embodiment. The system structure of one receiving antenna, the actual number of transmitting antennas and receiving antennas can be flexibly selected according to the actual situation, and is not limited to the number setting in this embodiment.

[0038] It can be seen from the figure that the microstrip array antenna system in this embodiment mainly includes a dielectric substrate and multiple antennas arranged on its surface. A conductive ground plate (not marked in the figure) is also provided on the back of the dielectric substrate 1 . In this embodiment, in order to achieve better system performance, the dielectric substrate 1 adopts the dielectric substrate model Rogers3003, the dielectric constant is 3, and the thickness is 0.127mm. The parameters of the above dielectric substrate can be selected according to the actu...

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a microstrip array antenna system based on a 77GHz millimeter wave radar. Background technique [0002] Millimeter-wave radar is currently widely used in the field of traffic detection, and 77GHz millimeter-wave radar has great advantages in terms of volume, detection accuracy and detection distance, because the 77GHz radar microstrip antenna is easier to Narrow beam and high gain are achieved with a small antenna volume. Because of these characteristics, 77GHz-based millimeter-wave radars will become standard for active safety. The corresponding wavelength of the 77GHz radar is shorter, and the electromagnetic radiation electromagnetic circuit processing technology and precision of the electromagnetic radiation generated by the electromagnetic wave have a very high level. Taking the antenna as an example, the microstrip array antenna needs to be printed directly on the surfac...
