Abstract

The invention discloses a feedback network which comprises a first energy coupling part, a phase shift wire and a second energy coupling part. The first energy coupling part is arranged on a first feed line of an array antenna or is arranged in the preset range of a first antenna unit of the array antenna and is used for carrying out coupling on signals sent by the first antenna unit, and first coupling signals are obtained. The phase shift wire is connected with the first energy coupling part and is used for receiving the first coupling signals, and the first coupling signals are subjected to phase adjusting and then are output. The second energy coupling part is arranged on a second feed line of the array antenna or is arranged in the preset range of a second antenna unit of the array antenna and is used for carrying out coupling on the first coupling signals after phase adjusting, and second coupling signals are obtained. The second coupling signals are sent to the second antenna unit through the second feed line to offset reflecting signals received by the second antenna unit. The invention further discloses the array antenna. Array antenna standing waves can be improved, and the bandwidth of the array antenna is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a feedback network and an array antenna. Background technique [0002] With the rapid development of mobile communication technology, the transmission range of signals is wider and wider, and the transmission speed is faster and faster. In a mobile communication system, the transmission and reception of wireless signals are realized by antennas. Therefore, the antenna plays a very important role for the mobile communication network. If the antenna is not properly selected, such as the type of antenna, the location of the antenna, or the parameter setting of the antenna, it will directly affect the communication quality of the entire mobile communication network. Among them, the input impedance of the antenna is one of the main parameters that characterize the performance of the antenna. In the mobile communication network, if the impedance of the antenna and the feeder do...
