Description
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 volume of the CPE is limited, which affects the space for installing the antenna inside the CPE, thereby affecting the performance of the CPE.

Therefore, under the condition that the basic performance of the antenna is not large, the size of the radiating body 40 can be greatly reduced, the overall size of the customer front equipment is reduced, the isolation degree between the radiating bodies 40 can be improved, or more radiating bodies can be placed, and the radiation performance of the antenna is further improved.
The client front-end device provided by the embodiment of the present application is described in detail above. The principles and implementations of the present application are described herein using specific examples, which are presented only to aid in understanding the present application. Meanwhile, for those skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
