Embodiment Construction

[0013] 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.

[0014] In the field of vehicle antenna design, the traditional solution to improve antenna isolation is to increase the spatial distance between the two antennas, which will increase the size of the shark fin or T-BOX box (Telematics-BOX, vehicle-mounted intelligent terminal) , not only increases the cost but also affects the appearance design.

[0015] See figure 1 , in order to solve the above technical problems, this embodiment provides a vehicle-mounted...

Abstract

The invention relates to the technical field of vehicle-mounted antennas, and concretely relates to a vehicle-mounted 5G antenna structure capable of improving isolation. The 5G antenna structure comprises a T-BOX, and a 5G antenna group and a GNSS antenna which are attached to a PCB of the T-BOX, wherein the 5G antenna group comprises a plurality of 5G antennas; and at least one straight groove is formed in the floor of the PCB between two adjacent 5G antennas. The invention aims to provide the vehicle-mounted 5G antenna structure capable of improving isolation. By adopting the technical scheme provided by the invention, the technical problem that the size of a shark fin or the T-BOX box is increased due to the fact that a traditional antenna is used for meeting 5G antenna communication is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle antennas, in particular to a vehicle 5G antenna structure with improved isolation. [0002] technical background [0003] 5G (5th Generation, the fifth generation of mobile communication) technology is the hottest topic in the current technology industry, and the development of 5G technology will bring huge changes to society. The three major characteristics of 5G technology include large bandwidth, high reliability and low latency, and large-scale connections. Among them, the characteristics of large bandwidth can bring faster data transmission rate, which greatly improves the user's online experience; the characteristics of high reliability and low delay make it possible to realize technologies such as telemedicine and automatic driving; Networking, industrial Internet, etc. bring possibilities. [0004] In order to achieve a faster transmission rate, 5G technology requires more antennas to sen...
