Technical Field
The invention relates to the technical field of vehicle-mounted antennas, in particular to a vehicle-mounted 5G antenna structure for improving isolation.
Technical Field
5G (5th Generation, fifth Generation mobile communication) technology is the most popular topic in the current technology industry, and the development of the 5G technology will bring huge changes to the society. The 5G technology has three characteristics, including large bandwidth, high reliability, low time delay and large-scale connection. The characteristic of large bandwidth can bring faster data transmission rate, and greatly improve the user internet experience; the characteristics of high reliability and low time delay bring possibility for the realization of technologies such as remote medical treatment, automatic driving and the like; the characteristic of large-scale connection brings possibility for realizing Internet of vehicles, industrial Internet and the like.
5G technology requires more antennas to transmit and receive wireless signals in order to achieve faster transmission rate, and the terminal requires at least 4 antennas supporting 5G frequency bands. The number of antennas is increased and the antennas coexist in the same environment, and the antennas are easy to interfere with each other due to poor isolation control. Therefore, it is becoming more and more important to improve the isolation performance of the antennas in a multi-antenna environment and further avoid mutual interference between the antennas.
In the field of vehicle-mounted antenna design, the traditional scheme for improving the isolation of the antenna is realized by increasing the spatial distance between two antennas, and the size of a shark fin or a T-BOX (Telematics-BOX) BOX is increased, so that the cost is increased and the appearance design is influenced.

In order to solve the technical problem, the invention provides a vehicle-mounted 5G antenna structure for improving isolation, which comprises a T-BOX, a 5G antenna group and a GNSS antenna, wherein the 5G antenna group and the GNSS antenna are attached to a PCB (printed Circuit Board) of the T-BOX; the 5G antenna group comprises a plurality of 5G antennas; at least one straight groove is formed in the floor of the PCB between two adjacent 5G antennas.
Preferably, the 5G antenna group includes four groups of 5G antennas.
Preferably, the number of the straight grooves is four.
Therefore, by applying the technical scheme provided by the invention, the isolation performance between the antennas is improved through the slotting of the PCB floor, and the floor slotting can separate the distributed currents on the floors of two adjacent antennas on one hand; on the other hand, the return path of the current is increased, thereby reducing the intensity of the distributed current flowing from one antenna to another on the floor. Therefore, the antenna isolation performance can be improved in a compact environment with multiple antennas, and the problem of mutual interference among the antennas is solved.

It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the field of vehicle-mounted antenna design, the traditional scheme for improving the isolation of the antenna is realized by increasing the spatial distance between two antennas, and the size of a shark fin or a T-BOX (Telematics-BOX) BOX is increased, so that the cost is increased and the appearance design is influenced.
Referring to fig. 1, in order to solve the above technical problem, the present embodiment provides a vehicle-mounted 5G antenna structure for improving isolation, in which a structure of a T-BOX built-in antenna is adopted for a 5G antenna in the scheme.
For this reason, the vehicle-mounted 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. The 5G antenna group comprises a plurality of 5G antennas; at least one straight groove is formed in the floor of the PCB between two adjacent 5G antennas.
Preferably, the 5G antenna group includes four groups of 5G antennas, i.e., 5G antenna 1, 5G antenna 2, 5G antenna 3, and 5G antenna 4. The design of the four groups of 5G antennas meets the requirement that a 5G frequency band supports 4x4MIMO (Multiple Input Multiple Output). Correspondingly, the number of the straight grooves is four.
According to the antenna principle, the plane of the PCB floor is also a part of the antenna, and the floor can participate in the radiation of electromagnetic waves, so that high-frequency current distribution can also be generated on the floor. The scheme provided by the embodiment is that the isolation performance between the antennas is improved through the PCB floor slotting, and the floor slotting can separate the distributed currents on the floors of two adjacent antennas on one hand; on the other hand, the return path of the current is increased, thereby reducing the intensity of the distributed current flowing from one antenna to another on the floor.
As shown in fig. 1, the slot 1 mainly improves the isolation between the 5G antenna 1 and the 5G antenna 2, and also improves the isolation between the 5G antenna 1 and the 5G antenna 2; the slot 2 is mainly used for improving the isolation between the 5G antenna 4 and the 5G antenna 3 and also improving the isolation between the 5G antenna 1 and the 5G antenna 3; slot 3 and slot 4 primarily improve the isolation between 5G antenna 2 and 5G antenna 3 while also improving the isolation between 5G antenna 2 and 5G antenna 4. Wherein the size of the slot can be adjusted according to specific environments.
Therefore, by applying the technical scheme provided by the invention, the isolation performance between the antennas is improved through the slotting of the PCB floor, and the floor slotting can separate the distributed currents on the floors of two adjacent antennas on one hand; on the other hand, the return path of the current is increased, thereby reducing the intensity of the distributed current flowing from one antenna to another on the floor. Therefore, the antenna isolation performance can be improved in a compact environment with multiple antennas, and the problem of mutual interference among the antennas is solved.
The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
