Abstract

A beam scanning antenna, a microwave system, and a beam alignment method, the method includes: the switching control module instructs the feed switching module to enable each feed in the multi-feed antenna, so that the feeds perform signal quality detection respectively; The multi-feed antenna includes an aperture unit and at least two feed sources; the feed sources are used to radiate electromagnetic wave signals; the feed source switching module includes a multi-way switch, each of the feed sources is respectively connected to the feed source switching module The switching control module obtains the result of the signal quality detection of each feed source; the switching control module selects the feed source with the best signal quality according to the result of the signal quality detection as a work feed.

Description

technical field [0001] The invention relates to the communication field, in particular to a beam scanning antenna, a microwave system and a beam alignment method. Background technique [0002] In microwave communication applications, high-gain antennas are usually used to obtain longer transmission distances or avoid interference. However, the beam angle of high-gain antennas is very small, and it is difficult to install and align. In addition, when encountering strong winds and other conditions, the slight shaking of the antenna will cause the link to be interrupted. [0003] In the prior art, antenna equipment is installed on a microwave tower that is difficult to shake, and is reinforced by a reinforcement device. [0004] However, in practical applications, the installation environment of microwave towers is relatively limited, and not all scenarios are available. For example, in urban applications, it may only be installed on poles or roofs; Difficulty and installatio...
