FEED NETWORK AND ANTENNA

摘要

A feed network and an antenna are provided in the embodiments of the present invention, for reducing the passive intermodulation interference, improving the reliability and stability of mobile communication quality of the antenna. The feed network includes at least two separate radio frequency transmission areas, at least two signal lines are built in at least one radio frequency transmission area of the radio frequency transmission areas, and the at least two separate radio frequency transmission areas are separated by a metal interlayer. One physical surface of the metal interlayer is exposed to one radio frequency transmission area of the at least two separate radio frequency transmission areas, and the other physical surface of the metal interlayer is exposed to the other radio frequency transmission area of the at least two separate radio frequency transmission areas. In the feed network of the present invention, the radio frequency transmission areas are separated by the metal interlayer instead of being connected by bolts or rivets; thus passive intermodulation interference caused by metal connection is reduced, and the reliability and stability of antennas, the criterion of Received Total Wide band Power (RTWP) and Received Signal Strength Indication (RSSI) of a system, and quality of mobile communication are improved.
