Problems solved by technology

[0003] However, the rear focus antenna in the above-mentioned antenna system is actually a horn antenna. The gain of the horn antenna is relatively high, but the receiving area is small, and the reflection coefficient on its mouth surface is small. The feed source of the sub-radiating back-fed parabolic receiving antenna, and this kind of back-focus antenna is large in size and inconvenient to install, which will increase the volume of the entire antenna system and limit the application environment

Abstract

Provided are a vehicle-mounted array radar antenna and a vehicle lamp. The vehicle-mounted array radar antenna is embedded in a shade of a vehicle lamp. The vehicle-mounted array radar antenna comprises a microstrip patch antenna array, a media substrate and a reflecting surface. The microstrip patch antenna array is positioned at and connected to an upper surface of the media substrate. The reflecting surface is positioned under and connected to a lower surface of the media substrate. The vehicle-mounted array radar antenna has a low profile and a simple structure and can be conveniently installed in the shade of the vehicle lamp without needing any additional material. Moreover, the use of a microstrip array antenna satisfies the requirements of high gain and a small angle.

Description

technical field [0001] The present application relates to the technical field of automobile manufacturing, in particular to a vehicle array radar antenna and a vehicle light. Background technique [0002] A vehicle-mounted millimeter wave anti-collision radar antenna system in the prior art includes a rear focus antenna, a lens unit is fixed at the open end of the rear focus antenna, and a microstrip antenna is fixed at the narrow end; the lens unit includes a transmitting lens and The receiving lens, the microstrip antenna includes a transmitting antenna and a receiving antenna, and the receiving antenna irradiates the receiving lens through three microstrip patch feeds parallel in the horizontal direction; the above-mentioned transmitting antenna is connected with a power amplifier, a directional coupler, a voltage-controlled oscillator and The linear modulator and the receiving antenna are sequentially connected with a low-noise amplifier, a low-pass filter and an interme...
