Abstract

The invention discloses a multifunctional vehicle-mounted combined antenna and a vehicle. The multifunctional vehicle-mounted combined antenna comprises a dielectric substrate, wherein the middle region of the dielectric substrate is provided with a navigation antenna, the dielectric substrate is further provided with an LTE-MIMO antenna, a V2X-MIMO antenna, a WIFI master antenna and a WIFI slave antenna, the LTE-MIMO antenna comprises two LTE antennas, and the V2X-MIMO antenna comprises a master V2X antenna and a slave V2X antenna; and the navigation antenna, the two LTE antennas, the master V2X master antenna, the slave V2X slave antenna, the WIFI master antenna and the WIFI slave antenna are respectively fed through coaxial cables. The LTE-MIMO antenna, the V2X-MIMO antenna, the WIFI master antenna, the WIFI slave antenna and the navigation antenna are integrated on the dielectric substrate, so that simultaneous working of multiple frequency bands such as 2G / 3G / 4G / 5G and the like can be realized in a limited space, and the multifunctional vehicle-mounted combined antenna adapts to the intelligent development trend of vehicles.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation equipment, in particular to a multifunctional vehicle-mounted combined antenna and a vehicle. Background technique [0002] The development of vehicle antenna mainly goes through two stages: the traditional vehicle AM / FM antenna and the existing shark fin vehicle antenna. At present, cars are developing in the direction of intelligent terminals, not just driving tools. More and more antennas are required to be integrated in the vehicle to obtain vehicle, road, communication, positioning, environmental perception, information processing and other information. [0003] The length of the traditional car AM / FM antenna is generally one-quarter working wavelength or one-half working wavelength, which can achieve omnidirectional radiation on the horizontal plane, but the antenna size is too large due to the low working frequency band, which seriously affects the appearance of ...

AI Technical Summary

Problems solved by technology

[0003] The length of the traditional vehicle-mounted AM / FM antenna is generally 1 / 4 or 1 / 2 of the working wavelength, which can realize omnidirectional radiation on the horizontal plane, but the antenna size is too large due to the low working frequency band, which seriously affects the appearance of the car ; Multiple antennas can be assembled in the shark fin antenna, but most of them are installed on the roof of the car, but it brings a huge challenge to the production and processing technology. Considering the wind resistance problem during the driving process of the vehicle, the size of the shark fin antenna It is also limited, causing the mutual interference of different antennas, so too many antennas cannot be integrated. At the same time, the shark fin antenna is exposed to the outside of the vehicle and is vulnerable to direct sunlight, which makes the internal temperature too high, which affects the performance of the antenna. Shark fin antennas cannot adapt to the development trend of automobile intelligence
