Title:
FEED NETWORK, BASE STATION ANTENNA AND BASE STATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/135002
Kind Code:
A1
Abstract:
A feed network, a base station antenna and a base station device. The feed network comprises a feed measurement unit, and a first feed point and a second feed point, which are located on the same feed link, wherein the feed measurement unit determines, when the feed link is in a preset working state, the standing-wave ratio of the feed link according to a first electrical signal at the first feed point and a second electrical signal at the second feed point; and if the standing-wave ratio of the feed link does not match a standing-wave ratio corresponding to the preset working state, it is determined that the connection of the feed link is abnormal. By means of arranging a feed measurement unit in a feed network, not only can a cable connection inside a base station antenna be calibrated in advance before the base station antenna leaves a factory, but a cable connection problem outside the base station antenna can also be detected after an external device is connected, such that the delivery or mounting of a base station device without a cable connection error is facilitated, and the probability of the base station device being returned to the factory for maintenance and a user redeploying a base station antenna are reduced.
