Shark fin antenna with LTE + dual GNSS function

Abstract

The invention discloses a shark fin antenna with LTE + dual GNSS function, characterized by, include an antenna housing, radio antenna assembly, A LTE main antenna oscillator, an LTE slave antenna oscillator, an amplify chassis, an LTE slave antenna chassis, a dual GNSS antenna assembly, a chassis, a cable assembly, a radio antenna assembly, and an amplifier chassis are arrange on that chassis, the dual GNSS antenna assembly is arranged on the outside of the amplifier chassis, and the radio antenna assembly is printed with spiral copper foil outside the medium; The copper foil is covered withan insulating protective layer; LTE main antenna oscillator, the LTE is fed from the antenna oscillator at the lower end of its dielectric body, A LTE mast antenna vibrator is respectively arranged onthat amplify bottom plate, and an LTE slave antenna vibrator is respectively arranged on the LTE slave antenna bottom plate. A receiving antenna assembly, an LTE master antenna vibrator, an LTE slaveantenna vibrator, and a dual GNSS antenna assembly are respectively connected with the over-cable assembly to output the receive signal to the vehicle-mounted host computer. The invention has simplestructure and convenient use and installation.

Description

technical field [0001] The invention relates to the technical field of automotive communication signal antennas, in particular to an antenna with LTE+dual GNSS functions. Background technique [0002] At present, with the rapid development of the automobile industry, people have higher and higher requirements for the appearance and function of the car. The traditional single radio function is far from meeting the market demand. Various mobile Internet communications (single (3G) frequency band) 1. The function of a single GNSS cannot meet the market demand, so the introduction of dual 4G LTE frequency bands and dual GNSS requires the design of automotive antennas. Under the premise of satisfying multiple functions, the antenna shape requirements also make various antennas tend to be miniaturized, which is convenient Integrated in the shark fin shell, the key to the reception quality of the mobile internet communication signal lies in the design technology of the receiving an...
