Description
Technical Field
[0001] The utility model relates to the technical field of automobile antennas, in particular to an integrated shark fin antenna device. Background Art
[0002] With the rapid development of modern communication technology, automotive antennas must not only meet basic radio and navigation functions but also support multiple functions, such as mobile communications and digital audio broadcasting (DAB). Traditional automotive antenna designs often adopt a decentralized layout, with each function corresponding to a separate antenna. This not only takes up space on the vehicle's exterior, affecting its aesthetics, but also increases the complexity of installation and maintenance. Therefore, there is an urgent need for a multifunctional automotive antenna device.
[0003] Against this backdrop, the integrated shark fin antenna device emerged. This antenna device integrates a GNSS (Global Navigation Satellite System) antenna module and a multi-function antenna module (including a DAB antenna, AM / FM radio antenna, and LTE communication antenna) into a compact housing. The housing is designed in the shape of a shark fin, which is both aesthetically pleasing and aerodynamic, reducing wind resistance during vehicle operation.
[0004] However, existing integrated shark fin antenna devices still face several challenges in design and implementation. First, there's the issue of effectively integrating multiple antenna modules within a limited space while ensuring electromagnetic compatibility between them. Second, the stability and reliability of the antenna mounting structure are crucial for ensuring antenna performance, but existing mounting structures are often complex, making them difficult to install and maintain. Furthermore, the layout and fixing method of the output cables are also significant factors affecting antenna performance and aesthetics.
[0005] Specifically, existing integrated shark fin antenna systems lack standardization and modularity in the design of their mounting brackets, making installation cumbersome and difficult to ensure secure. Furthermore, the mounting methods for antenna elements in multi-function antenna modules (such as DAB antennas, AM / FM radio antennas, and LTE communication antennas) lack flexibility, making them difficult to adapt to different vehicle models and installation requirements. Furthermore, the routing of output cables is often disorganized, which not only affects aesthetics but can also affect antenna performance due to interference between cables.
[0006] In response to the above problems, the present invention proposes an improved integrated shark fin antenna device, which aims to solve the problems existing in the prior art by optimizing the design of the mounting bracket, improving the stability and reliability of the antenna mounting structure, and rationally laying out the output lines, thereby providing a car antenna device with stable performance, easy installation, and beautiful and practical appearance.

[0010] The mounting bracket includes a first mounting bracket and a second mounting bracket; after the first mounting bracket is clamped with the second mounting bracket, antenna mounting areas for mounting a DAB antenna and an AM / FM radio antenna are formed therein; mounting buckles for mounting an antenna loading sheet are symmetrically provided on both sides of the antenna mounting area.
[0011] Both ends of the mounting bracket are provided with mounting slots; the LTE communication antennas are installed in the mounting slots.
[0012] The four corners of the mounting bracket are provided with mounting holes; the mounting holes are connected to the metal base by penetrating the PCB matching antenna amplifier circuit board through locking screws.
[0013] The DAB antenna and the AM / FM radio antenna are fixed in corresponding antenna installation areas in a spiral shape.
[0014] The metal base is provided with mounting posts corresponding to the GNSS antenna module and the multi-function antenna module respectively.
