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 ...
