MULTI-BEAM ANTENNA

WIPO Patent Application WO/2021/244047

A1

The present invention provides a multi-beam antenna, comprising an antenna array, a first feed network, and a second feed network. The antenna array is formed by mixing and arraying multiple first subarrays and multiple second subarrays; the first subarray is fed by the first feed network or the second feed network; the second subarray is fed by the second feed network or the first feed network; the first feed network comprises a first phase shift network, a phase balance circuit, and a first subarray feed network which are electrically connected in sequence; the second feed network comprises a second phase shift network and a second subarray feed network which are electrically connected in sequence. In this way, according to the present invention, the span of a horizontal wave width of a single beam can be converged within a reasonable range, thereby improving the coverage quality of the multi-beam antenna.
