Intelligent shark fin antenna

Abstract

The invention discloses a shark fin intelligent antenna, and relates to the technical field of automobile antennas. The shark fin intelligent antenna comprises a shark fin shell and a base; the shark fin shell and the base form a shark fin type inner cavity, the inner cavity is internally provided with an LAN mainboard, the LAN mainboard is fixed on the base, the LAN main board is provided with a 5G main antenna, a 5G auxiliary antenna, a 5G-MIMO 1 antenna, a 5G-MIMO2 antenna, a GNSS antenna, a V2X-F antenna, a V2X-R antenna and a WIFI antenna. According to the shark fin type antenna, the eight antennas are arranged in total, through reasonable layout, the inner cavity space of the shark fin type antenna and different working frequency bands of the eight antennas are fully utilized, the physical distance among the eight antennas is increased, space coupling and surface wave coupling among the eight antennas are reduced, and the isolation degree among the antennas is good.

Description

technical field [0001] The invention relates to the technical field of automobile antennas, in particular to a shark fin smart antenna. Background technique [0002] At present, mainstream vehicle communication antennas are often designed in shark fins. At present, shark fin smart antennas are equipped with 2G / 3G / 4G main antennas, 2G / 3G / 4G diversity antennas, GNSS satellite positioning antennas, AM / FM radio antennas, etc. The arrival of 5G technology provides higher transmission rate and transmission quality: the blueprint of 5G network is 100 times the high rate of 4G, which will reach 10Gbit / s, low delay of less than 1ms, and high density supporting more than 100 billion connections And 1000 times the high capacity of 4G. It will be a trend to apply 5G antennas to vehicles to realize applications such as Internet of Vehicles and driverless driving. However, integrating 5G antennas into the shark fin shell saves procurement and use costs, and there is no need to find insta...

Problems solved by technology

[0003] As vehicle-mounted 5G and V2X technologies become increasingly mature, when more and more multimedia receivers, positioning and navigation receivers, and communication modules are integrated into a LAN motherboard, more antennas are needed to realize their functions, and the internal space of the shark fin However, it is necessary to integrate a variety of antennas, which will result in poor antenna isolation, crosstalk between signals, and affect antenna performance.
