Abstract

The invention provides an antenna device and a preparation method thereof, a radar and a terminal, belongs to the technical field of sensors, and can be applied to the field of automatic driving or intelligent driving. The antenna device comprises a first antenna array, the first antenna array comprises at least one antenna unit, the first antenna unit in the at least one antenna unit comprises afirst patch subunit and a first feeder line subunit, and the first feeder line subunit comprises a first feeder line and a second feeder line; a first included angle theta between the first patch sub-unit and the first feeder line meets the condition that 0< theta < 90 degrees; and a second included angle beta between the first feeder line and the second feeder line meets the condition that 0 < beta < 180 degrees. According to the embodiment of the invention, the 3dB beam width of the antenna structure can be expanded, the ADAS capability of the terminal in automatic driving or auxiliary driving is further improved, and the device can be applied to the Internet of Vehicles, such as vehicle external V2X, the inter-vehicle communication long-term evolution technology LTE-V, vehicle-vehicle V2V and the like.

Description

technical field [0001] The present application relates to the field of sensor technology, and more particularly, to an antenna device in the field of sensor technology, a preparation method thereof, a radar, and a terminal. Background technique [0002] With the development of society, smart terminals such as smart transportation equipment, smart home equipment, and robots are gradually entering people's daily lives. Sensors play a very important role in smart terminals. Various sensors installed on the smart terminal, such as millimeter-wave radar, lidar, camera, ultrasonic radar, etc., sense the surrounding environment during the movement of the smart terminal, collect data, and identify and track moving objects. And the recognition of static scenes such as lane lines and signs, and combined with navigator and map data for path planning. Sensors can detect possible dangers in advance and assist or even take necessary avoidance measures autonomously, effectively increasin...
