Problems solved by technology
[0003] The antenna design of traditional customer front-end equipment continues to evolve towards multi-polarization and high gain, but limited by regional regulations, there are clear restrictions on the gain of the transmitting antenna
At the same time, since the transmission and reception of the customer's front-end equipment use the same antenna, the index of the antenna is fixed, and the increase in the gain of the receiving antenna will cause the gain of the transmitting antenna to exceed the standard, which does not meet the requirements of the regulations.

Embodiment Construction
[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0023] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first antenna could be termed a second antenna, and, similarly, a second antenna could be termed a first antenna, without departing from the scope of the present application. Both the first antenna and the second antenna are antennas, but they are not the same antenna.

The invention provides an antenna assembly, a radio frequency system and client front-end equipment, and the antenna assembly comprises at least one antenna; a switch module which is correspondingly connected with each antenna and is used for receiving the switching control signal and selectively conducting the transmitting channel or the receiving channel of each antenna according to the switching control signal; and an attenuation network which is arranged in the transmitting channel and used for attenuating the antenna gain of a radio frequency signal transmitted by the antenna, so switching between the transmitting channel and the receiving channel can be dynamically achieved by arranging the attenuation network and the controllable switch module on the transmitting channel, and when the antenna assembly is switched to the transmitting channel, the transmitting gain of the antenna can be attenuated based on the attenuation network; when the antenna assembly is switched to the receiving channel, the receiving gain of the antenna is not changed, so that the maximization of the receiving gain can be realized on the premise of meeting the requirements of laws and regulations, and the optimal receiving performance of the antenna assembly is realized.
Description
technical field [0001] The present application relates to the technical field of radio frequency communication, and in particular relates to an antenna assembly, a radio frequency system and customer front-end equipment. Background technique [0002] With the development of Internet services, users have higher and higher requirements on the network quality of broadband Internet access. However, in order to ensure network quality, Customer Premise Equipment (CPE) may be set up in areas such as rural areas, towns, hospitals, units, factories, and communities. [0003] The antenna design of traditional customer front-end equipment continues to evolve towards the direction of multi-polarization and high gain, but limited by regional regulations, there are clear restrictions on the gain of the transmitting antenna. At the same time, since the customer's front-end equipment uses the same antenna for both transmission and reception, the index of the antenna is fixed, and the incre...
