Abstract

The invention provides a vehicle-mounted antenna. The vehicle-mounted antenna comprises a shark fin shell and an antenna device arranged in the shark fin shell, wherein the antenna device comprises afirst main board, a first 5G antenna, a second 5G antenna, a third 5G antenna and a fourth 5G antenna, the first main board is provided with a first side edge, a second side edge, a third side edge, afourth side edge and a first connecting line for connecting the third side edge and the fourth side edge, a first 5G antenna to a fourth 5G antenna are sequentially arranged on an upper surface of the first mainboard along a first connecting line, the first 5G antenna is close to the fourth side edge, the fourth 5G antenna is close to the third side edge, the first 5G antenna is perpendicular toor approximately perpendicular to the first connecting line, and the second 5G antenna to the fourth 5G antenna are located in a first plane which is perpendicular to or approximately perpendicular toan upper surface of the first mainboard and coincides with or approximately coincides with the first connecting line. The shark fin antenna ingeniously utilizes the large space at a tail end of the shark fin, effectively utilizes the internal space of the shell, increases the isolation degree between the antennas, and is compact in structure and more reasonable in overall layout.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to vehicle-mounted antennas. Background technique [0002] An antenna is a device used to transmit or receive radio waves and is widely used in systems such as radio and television, point-to-point radio communications, radar, and space exploration. Vehicle-mounted antennas are antenna systems installed on cars. Traditional vehicle-mounted antennas include braided antennas and short rod antennas. Shark-fin-type vehicle-mounted antennas developed in recent years are popular among consumers and manufacturers for their simple and stylish appearance. [0003] However, the existing shark-fin vehicle-mounted antenna is limited by volume, and the internal layout of the antenna is unreasonable, which is likely to cause some radiation interference and mutual interference between antennas, thereby affecting the performance of the antenna. Contents of the invention [0004] The pu...
