Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] At present, the ETC equipment has the following technical problems: ETC box + antenna + bank card are placed on the front windshield, the size is too large, which affects the neatness and beauty of the car; the ETC antenna design is easily disturbed inside the box, and the design of the ETC circuit PCB board is complicated At the same time, it limits the flexibility of antenna design; there is a risk of fraud.

[0026] Such as Figure 1-3 As shown, i...

Abstract

The invention relates to the technical field of vehicle-mounted shark fin antennas, in particular to a shark fin antenna structure with an ETC function. The shark fin antenna structure comprises a shark fin located at the top of a vehicle, an ETC antenna and an ETC box, the ETC antenna is fixedly arranged in the shark fin, and the ETC box is arranged in the vehicle. The objective of the inventionis to provide the shark fin antenna structure with the ETC function. With the adoption of the technical scheme provided by the invention, the technical problems that an existing ETC device is large insize, signals are easily interfered, and illegal swiping exists, are solved.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted shark fin antennas, in particular to a structure of a shark fin antenna with an ETC function. [0002] technical background [0003] With the increase in the number of cars, more and more people choose to travel by car, and the emergence of ETC (Electronic Toll Collection, that is, non-stop electronic toll collection system) has also largely relieved the pressure of congestion at expressway intersections. More and more vehicles choose to install ETC equipment in order to pass through high-speed toll intersections more quickly. ETC adopts the technology of DSRC (Dedicated Short Range Communication, dedicated short-range communication), and the working frequency is 5.8GHz. [0004] The current ETC devices are boxes + antennas + bank cards placed on the front windshield, because the current ETC devices are all post-installed products, so the design is not very flexible. The state has recentl...
