Problems solved by technology

The increase in the number of antennas will bring many problems such as crowded antennas inside the T-BOX antenna, poor isolation, and signal interference.

5G applications have higher requirements on the signal quality and stability of the antenna. The communication antenna data required inside the T-BOX antenna has increased. With the development of automobile intelligence, the T-BOX antenna has the functions of wireless local area network, mobile network, and high-precision positioning system. Antenna; Bluetooth antenna is also added to realize keyless entry and other functions and V2X antenna to realize Internet of Things connection. For example, according to the traditional T-BOX design, the difficulty of T-BOX internal PCB design is greatly increased, and the isolation of the antenna will be further deteriorated

[0004] At present, if the existing 5G combined antenna is designed according to the traditional T-BOX design technology, the 5G MIMO multi-antenna system is designed on the internal PCB board of the T-BOX, which will be limited by the size of the PCB, and more antennas will be assembled on the T-BOX antenna Internally, the distance between the antennas is too close, and the antennas will be coupled to each other, which will easily reduce the antenna efficiency
