Abstract

The invention relates to an active single frequency antenna system, which comprises a passive antenna and an active circuit, wherein the passive antenna is used for radiating an electromagnetic wave signal; the active circuit is connected to the passive antenna and comprises a connection port, a radio frequency coupler, a radio frequency transmitting and receiving module and a detection control module; the radio frequency transmitting and receiving module, the radio frequency coupler and the connection port are connected in sequence for realizing a transmitting and receiving process of a radio frequency signal; the detection control module is connected to the radio frequency transmitting and receiving module and is used for controlling the radio frequency transmitting and receiving module to receive or transmit the radio frequency signal; the radio frequency coupler is used for collecting the radio frequency signal. The radio frequency transmitting and receiving module comprises a low noise amplifier, and the radio frequency transmitting and receiving module amplifies the received radio frequency signal through the low noise amplifier and transmits the received radio frequency signal to the connection port in a process of receiving the radio frequency signal.

Description

technical field [0001] The invention relates to the communication field, in particular to an active single-frequency antenna system. Background technique [0002] Existing Wi-Fi antennas are generally passive designs, that is, the effective radiation of the antenna is realized through the resonance of the antenna, and the gain of the antenna is increased by means of unit arrays. This method can improve the strength of the wireless signal, but for some For high-end Wi-Fi routers, since the number of antennas is as many as 8 or more, the antennas of different frequency bands must maintain a certain distance to meet the isolation requirements. [0003] In order to ensure the distance between different antennas, the traditional passive antenna design usually needs to add a relatively long RF jumper between the passive antenna and the Wi-Fi active RF port, but this will cause a relatively large RF dropout , and the RF dropout will directly deteriorate the uplink noise figure, th...
