Description

Customer premises equipment

The application discloses a divisional application of China patent application with the name of 'customer front-end equipment' which is filed by China patent office, application number 201911421876.2 and the name of China patent application on the 12 th month 31 of 2019.

Technical Field

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

Background

The CPE (Customer Premise Equipment ) is a mobile signal access device that receives mobile signals and forwards the mobile signals as WIFI signals, and is also a device that converts high-speed 4G or 5G signals into WIFI signals, and can support a large number of mobile terminals that can access the internet simultaneously. The CPE can be widely applied to wireless network access in rural areas, towns, hospitals, units, factories, communities and the like, and the cost for laying wired networks can be saved.

In the case of a relatively large distance or a relatively large number of obstacles, signal coverage of the base station may easily occur as a signal blind spot. At these blind corners, a terminal device such as a smart phone cannot receive the base station signal. The CPE can perform secondary relay on the base station signal, and it converts the received signal into a Wi-Fi signal, and provides the Wi-Fi signal to the devices nearby. Compared with terminal equipment such as a smart phone, a notebook computer and the like, the CPE antenna has stronger gain and higher power, and the signal receiving and transmitting capability of the CPE antenna is stronger than that of the smart phone. Therefore, there are places where the smart phone has no signal and the CPE may have a signal. The CPE can change the network signal of the operator into a Wi-Fi signal, and more devices such as a smart phone, an ipad, a notebook computer and the like can access the Internet by means of the CPE.

The CPE has a limited internal space, and in order to improve portability of the CPE, there is often a certain requirement on the volume of the CPE. However, the volume of the CPE is limited, which affects the space in which the antenna is installed inside the CPE, thereby affecting the performance of the CPE.

Disclosure of Invention

The embodiment of the application provides customer premises equipment, which improves the communication performance of the customer premises equipment.

The embodiment of the application discloses customer premises equipment, comprising:

the radiating fin comprises a substrate and a plurality of fins arranged on the substrate at intervals; and

the antenna radiator is arranged on the fin and comprises a grounding point connected with the fin.

In the embodiment of the application, the grounding point of the antenna radiator is connected with the radiating fin, so that the radiating fin can form a part of the antenna structure, and compared with the mode that the antenna structure is arranged outside the radiating fin, the integral space of the customer front-end equipment can be saved, and the size of the customer front-end equipment can be reduced under the condition that the customer front-end equipment has excellent communication performance. Or the communication performance of the client front-end equipment can be improved under the condition of keeping a certain volume of the client front-end equipment.

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

It can be appreciated that, in the embodiment of the present application, the heat dissipation fins 500 are disposed on two sides of the circuit board 700, and the two heat dissipation fins 500 can be respectively abutted to two opposite sides of the circuit board 700, so that the purpose of heat dissipation can be achieved from 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 being disposed on the fins 540 of the heat sink 500. The number of antenna radiators 300 may also be one, two, three, four or more.

With continued reference to fig. 22-23, for example, 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 two fins 540 located at the outermost side among all fins 540. The two antenna radiators 300 may be located opposite. Of course, the positions of the two antenna radiators 300 may not be opposite, i.e., the two antenna radiators 300 may be located at opposite ends of the heat sink 500.

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

With continued reference to fig. 24, for example, four antenna radiators 300 may be disposed on two heat sinks 500, wherein two antenna radiators 300 are disposed on the same heat sink 500 and two other antenna radiators 300 are disposed on another heat sink 500.

The embodiment of the present application may define 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 position of the first heat sink 500, and the third and fourth antenna radiators 300 and 300 may be located at the same end position 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 antenna radiator 300 and the third antenna radiator 300 are symmetrically disposed with respect to the circuit board 700, and the second antenna radiator 300 and the fourth antenna radiator 300 are symmetrically disposed with respect to the circuit board 700.

In some embodiments, a portion of the antenna radiator 300 may protrude from the end of the fin 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 excitation unit 320 may also be referred to as a feeding unit, where the excitation unit 320 has a feeding point 322, and the feeding point 322 may be electrically connected to the circuit board 700, and may be a coaxial line or a spring. The parasitic element 340 may also be referred to as a parasitic stub, the parasitic element 340 being directly connected to the heat sink 500, such as the parasitic element 340 being directly connected to the fin 540 of the heat sink 500. The parasitic element 340 has a ground 342, and the ground 342 may be connected to the fin 540 to ground the antenna radiator 300. Therefore, in the embodiment of the present application, the grounding 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 is used as the ground of the antenna radiator 300, and the heat sink 500 is used as a part of the radiation of the antenna radiator 300, so that the radiation efficiency can be improved under the condition of ensuring the wider working bandwidth of the antenna radiator 300. Therefore, the embodiment of the application can improve the communication performance of the client front-end equipment.

In addition, the grounding point 342 of the antenna radiator 300 is directly connected to the fin 540 of the heat sink 500, so that the size of the antenna radiator 300 can be saved. For example, the length of the grounding point of the antenna radiator is 120 mm and the width of the grounding point of the antenna radiator is 15 mm, and the length of the antenna radiator is 70 mm and the width of the antenna radiator is 30 mm by connecting the grounding 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 performances of the antenna radiators are not greatly different, the embodiment of the application can greatly save the size of the antenna radiator so as to reduce the whole volume of the customer front-end equipment. But also can improve the isolation of the antenna radiators 300 from each other or can place more antenna radiators to further improve radiation performance.

To further describe the differences between embodiments of the present application and not connecting the ground point of the antenna radiator to the heat sink, reference is made below to comparison in terms of parameters and efficiency.

Referring to fig. 25, fig. 25 is a diagram showing a comparison between S-parameters of an antenna radiator and S-parameters of an on-board antenna according to an embodiment of the application.
