Abstract: An antenna unit and an antenna array. The antenna unit includes M layers of cross metal patches, M layers of dielectric substrates, and a metal ground layer, where M is an integer greater than 1. In addition, an ith-layer dielectric substrate is disposed between an ith-layer cross metal patch and an (i+1)th-layer cross metal patch. The ith-layer cross metal patch, the ith-layer dielectric substrate, and the (i+1)th-layer cross metal patch are sequentially stacked, and i is an integer ranging from 1 to M−1. An Mth-layer cross metal patch, an Mth-layer dielectric substrate, and the metal ground layer are sequentially stacked. The antenna unit and the antenna array formed by units may have a good polarization feature, a relatively wide operating bandwidth, and a relatively good phase shift feature.

Abstract: Embodiments of the present invention disclose an interleaved polarized multi-beam antenna, including: at least one dual-polarized antenna element, where the dual-polarized antenna element includes a +45-degree-polarized first antenna element and a −45-degree-polarized second antenna element; and a first Butler matrix and a second Butler matrix, where the first Butler matrix is connected to the first antenna element so that the first antenna element transmits a first target beam, and the second Butler matrix is connected to the second antenna element so that the second antenna element transmits a second target beam. The first target beam and the second target beam in the embodiments are alternately arranged, and any two adjacent first target beam and second target beam have different polarization characteristics; therefore, complexity, a loss, and costs of implementation of a Butler matrix can be effectively reduced, and interference between adjacent multiplexed beams can be effectively decreased.
