Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted antennas, and specifically to a vehicle-mounted T-BOX antenna structure and a vehicle Background Art

[0002] With the rapid development of autonomous driving technology and mobile communication technology, especially the advent of 5G communication and Internet of Vehicles technology, the automotive field has more and more requirements for wireless communication functions, especially the increasing demand for high-speed and low-latency wireless communication. In order to meet the needs of wireless communication functions, antennas are an indispensable part. Antennas are devices that effectively transmit and receive electromagnetic wave signals, and they are very sensitive to the surrounding environment, especially the metal environment. Therefore, the layout position of the antenna body environment is critical to the performance of the antenna.

[0003] The current requirements for wireless communication functions in vehicle bodies are increasing day by day, such as 4G / 5G communication, GNSS (Global Navigation Satellite System) high-precision positioning navigation, V2X (Vehicle to Everything) car networking, AM / FM radio broadcasting, WIFI / BT functions, etc. More functions mean more antennas. As the number of antennas in the flat-panel T-BOX increases, and in order to meet the heat dissipation requirements of the miniaturized T-BOX, more and more metal is added to the box, while the size of the entire flat-panel T-BOX is limited, which results in the spacing of the antennas in the T-BOX being severely restricted by the environment, making it difficult to achieve high isolation requirements.
