Abstract

The present invention provides a vehicle-mounted array radar antenna and an automotive lamp. The vehicle-mounted array radar antenna is embedded in the lampshade of the automotive lamp; and the vehicle-mounted array radar antenna includes a microstrip patch antenna array, a dielectric substrate, and a reflection surface, wherein the microstrip patch antenna array is located at the upper surface ofthe dielectric substrate and is connected with the upper surface of the dielectric substrate, and the reflection surface is located at the lower surface of the dielectric substrate and is connected with the lower surface of the dielectric substrate. The vehicle-mounted array radar antenna provided by the invention has the advantages of low profile, simple structure and convenient installation. The vehicle-mounted array radar antenna is embedded in the lampshade of the automotive lamp with no additional materials adopted; the microstrip array antenna is adopted, and therefore, requirements ofhigh gain and small angles can be met.

Description
