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.
