Description

Customer premises equipment

Technical Field

The application relates to the technical field of electronics, in particular to customer premises equipment.

Background

A CPE (Customer Premise Equipment) is a mobile signal access device that receives a mobile signal and forwards the mobile signal by using a wireless WIFI signal, and is also a device that converts a high-speed 4G or 5G signal into a WIFI signal, and the number of mobile terminals capable of accessing the internet at the same time is also large. The CPE can be widely applied to wireless network access in rural areas, towns, hospitals, units, factories, cells and the like, and the cost for laying a wire network can be saved.

When the distance is relatively long or there are many obstacles, signal blind spots are likely to occur in the coverage of the base station signal. In these blind spot corners, the terminal device, such as a smartphone, cannot receive the base station signal. The CPE can relay the base station signals for the second time, and the base station signals are changed into Wi-Fi signals to be provided for the equipment nearby. Compared with terminal equipment such as a smart phone and a notebook computer, the CPE antenna has stronger gain and higher power, and the signal transceiving capacity of the CPE antenna is stronger than that of the smart phone. So, there are places where the smartphone has no signal and the CPE may have a signal. The CPE can change network signals of an operator into Wi-Fi signals, and more devices such as a smart phone, an ipad and a notebook computer can surf the internet by means of the CPE.

The CPE has a limited internal space and there is often a certain requirement on the volume of the CPE in order to improve its portability. However, the limited size of the CPE may affect the space within the CPE where the antenna is installed, and thus the performance of the CPE.

I.e., one heat sink 500 is disposed on one side of circuit board 700 and the other heat sink is disposed on the other side of circuit board 700. Two heat sinks 500 are oppositely disposed with respect to circuit board 700, such as two heat sinks 500 symmetrically disposed with respect to circuit board 700. Each heat sink 500 may include a base 520 and a plurality of fins 540.

It can be understood that, the circuit board 700 is generally provided with circuit structures on both sides, and in the embodiment of the present application, the heat dissipation fins 500 are provided on both sides of the circuit board 700, and the two heat dissipation fins 500 can be respectively abutted to the two opposite sides of the circuit board 700, so that the purpose of heat dissipation can be achieved from the two sides of the circuit board 700, and the heat dissipation efficiency can be improved.

It should be noted that the two heat sinks 500 may be defined as a first heat sink 500 and a second heat sink 500, respectively.

With continued reference to fig. 22-24, the antenna radiator 300 may be disposed on the heat sink 500, such as the antenna radiator 300 disposed on the fin 540 of the heat sink 500. The number of the antenna radiators 300 may also be one, two, three, four or more.

Referring to fig. 22 to 23, for example, two antenna radiators 300 are provided, and the two antenna radiators 300 may be disposed on the same heat sink 500. Two antenna radiators 300 are located at both sides of the heat sink 500, such as one antenna radiator 300 is disposed on one fin 540, and two antenna radiators 300 are disposed on the two outermost fins 540 among all the fins 540. The two antenna radiators 300 may be located opposite to each other. Of course, the positions of the two antenna radiators 300 may not be opposite, that is, the two antenna radiators 300 may be located at opposite end positions of the heat sink 500.

It should be noted that the two antenna radiators 300 may be disposed on different heat sinks 500.

Referring to fig. 24, for example, four antenna radiators 300 are provided on two heat sinks 500, wherein two antenna radiators 300 are provided on the same heat sink 500, and two antenna radiators 300 are provided on another heat sink 500.

The present embodiment may define the four antenna radiators 300 as a first antenna radiator 300, a second antenna radiator 300, a third antenna radiator 300, and a fourth antenna radiator 300, wherein the first antenna radiator 300 and the second antenna radiator 300 may be located at both sides of the first heat sink 500, and the third antenna radiator 300 and the fourth antenna radiator 300 may be located at both sides of the second heat sink 500. The first and

second antenna radiators

300 and 300 may be located at the same end of the first heat sink 500, and the third and

fourth antenna radiators

300 and 300 may be located at the same end of the second heat sink 500. The two antenna radiators 300 on the first heat sink 500 and the two antenna radiators 300 on the second heat sink 500 may be symmetrical with respect to the circuit board 700. Such as the first and

third antenna radiators

300 and 300 being symmetrically disposed with respect to the circuit board 700 and the second and

fourth antenna radiators

300 and 300 being symmetrically disposed with respect to the circuit board 700.

In some embodiments, a portion of the antenna radiator 300 may protrude beyond an end of the paddle 540.

Each of the antenna radiators 300 of the embodiments of the present application includes an excitation unit 320 and a parasitic unit 340. The exciting unit 320 may also be referred to as a feeding unit, and the exciting unit 320 has a feeding point 322, and the feeding point 322 may be electrically connected to the circuit board 700, and may be in the form of a coaxial line or a spring sheet. The parasitic element 340, which may also be referred to as a parasitic stub, is attached 340 directly to the heat sink 500, such as the parasitic element 340 being attached 340 directly to a fin 540 of the heat sink 500. The parasitic element 340 has a ground point 342, and the ground point 342 may be connected to a fin 540 to realize grounding of the antenna radiator 300. Therefore, in the embodiment of the present application, the ground point 342 of the antenna radiator 300 is directly connected to the fin 540 of the heat sink 500, so that the heat sink 500 serves as the ground of the antenna radiator 300 and the heat sink 500 serves as a part of the radiation of the antenna radiator 300, and the radiation efficiency can be improved while ensuring a wider operating bandwidth of the antenna radiator 300. Therefore, the communication performance of the client front-end equipment can be improved.

In addition, the embodiment of the present application directly connects the ground point 342 of the antenna radiator 300 to the fin 540 of the heat sink 500, which can save the size of the antenna radiator 300. Such as the length of the ground point of the antenna radiator not connected to the heat sink being 120 mm and the width being 15 mm, the length of the antenna radiator being 70 mm and the width being 30 mm can be achieved by connecting the ground point 342 of the antenna radiator 300 to the fin 540 of the heat sink 500 according to the embodiment of the present application. Therefore, under the condition that the basic performance of the antenna radiating body is not large, the size of the antenna radiating body can be greatly saved, and the overall size of the client front equipment is reduced. But also the isolation between the antenna radiators 300 can be improved, or more antenna radiators can be placed, so as to further improve the radiation performance.

To further illustrate the differences between the embodiments of the present application and the case where the ground point of the antenna radiator is not attached to the heat sink, a comparison is made below in terms of parameters and efficiency.

Referring to fig. 25, fig. 25 is a graph comparing S-parameters of an antenna radiator and an on-board antenna according to an embodiment of the present disclosure. Wherein the on-board antenna is a structure in which it does not connect the ground point to the heat sink. As can be seen from fig. 25, the S parameter of the antenna radiator 300 of the embodiment of the present application is superior to that of the on-board antenna. It should be noted that the embodiment itself may be simply referred to as the present solution.

Referring to fig. 26, fig. 26 is a graph comparing the efficiency of the antenna radiator of the present application with the efficiency of the on-board antenna. Wherein the on-board antenna is a structure in which it does not connect the ground point to the heat sink. As can be seen from fig. 26, the efficiency of the antenna radiator 300 of the embodiment of the present application is higher than that of the on-board antenna. It should be noted that the embodiment itself may be simply referred to as the present solution.
