Problems solved by technology

[0002] In the field of prior art, the structure or material of the antenna components in the vehicle-mounted shark fin antenna generally has the following types: PCB, metal sheet, coil or spring, etc., and its shape is limited by the shape and outline of the antenna and the characteristics of the material itself. The space or material characteristics of the antenna shape cannot be fully and effectively used for design
[0003] Moreover, based on the unfavorable factors of this space, the performance of the antenna component itself may not fully meet the established requirements, and it needs to be compensated by some other components (such as LNA or low noise amplifier), and it also needs to be matched with it. Obtaining the performance parameters that meet the requirements or meeting the requirements of customers may take more time to test and verify, and relatively speaking, the development cycle will be extended
[0004] At the same time, due to the factors of the antenna material itself, the weight of the shark fin antenna body will increase virtually, which will increase the transportation cost accordingly.

Embodiment 1

[0055] Please refer to Figure 1 to Figure 3 , the present embodiment provides a vehicle-mounted shark fin antenna structure, which at least includes a layer of antenna housing 1, a conductive device, a bottom plate 4, and an antenna line 11 fixedly arranged on the surface of the antenna housing. The antenna line 11 is formed on the The inner wall of the antenna housing 1;

[0056] In the assembled state, the bottom plate 4 and the antenna housing 1 are enclosed to form an internal cavity, and the conductive device and the antenna line 11 are all located in the internal cavity, and the conductive device is arranged on the bottom plate 4, so that The conduction device is in contact with the antenna line 11 , and the conduction device is also in conduction with the circuit structure on the bottom plate 4 .

[0057] Four processes are introduced below, and the antenna line can be formed on the surface of the antenna housing through the following processes:

[0058] 1. First, ac...

Embodiment 2

[0083] Please refer to Figures 4 to 6 , The main difference between this embodiment and Embodiment 1 is that the number of the antenna housings is two layers, and the antenna lines are arranged on the outer wall of the inner antenna housing. In the embodiment, the number of the antenna housings is one layer, and the antenna lines are arranged on the inner wall of the antenna housings.

[0084] Based on the difference between the two embodiments, it can be deduced that the number of antenna housings can be more layers. That is, a vehicle-mounted shark fin antenna structure in the present invention at least includes at least one layer of antenna housing, a conductive device, a bottom plate 5 and an antenna line fixedly arranged on the surface of one layer of the antenna housing, and the antenna line is formed on the The surface of the antenna housing described in the first layer; in this embodiment, the antenna housing has two layers, namely antenna housing 1 and 2, antenna ho...

Abstract

The invention provides a vehicle-mounted shark fin antenna structure. The vehicle-mounted shark fin antenna structure at least comprises at least one antenna shell, a conduction device, a bottom plate and an antenna circuit. The antenna circuit is fixedly distributed on the surface of one antenna shell, wherein the antenna circuit is formed on the surface of the antenna shell. In the assembled state, an inner cavity is defined by the bottom plate and the outermost antenna shell. Both the conduction device and the antenna circuit are located in the inner cavity. The conduction device is arranged on the bottom plate and makes contact with and is connected with the antenna circuit. The conduction device is further connected with a circuit structure on the bottom plate.
