    Abstract: Embodiments of the present invention provide a beam forming network, including: a first 180-degree bridge for equal-power division, a 180-degree bridge for unequal-power division, a 90-degree phase shifter, and a second 180-degree bridge for equal-power division. A coupling port of a sum input port of the first 180-degree bridge for equal-power division is connected to a difference input port of the 180-degree bridge for unequal-power division, a straight-through port of the sum input port of the first 180-degree bridge for equal-power division is connected to an input port of the 90-degree phase shifter, an output port of the 90-degree phase shifter is connected to a difference input port of the second 180-degree bridge for equal-power division, and a straight-through port of a sum input port of the 180-degree bridge for unequal-power division is connected to a sum input port of the second 180-degree bridge for equal-power division.

    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: An antenna array, including at least two antenna bays. Operating frequency bands of all of the at least two antenna bays are the same, each antenna bay includes at least one transmit channel or receive channel, and each antenna bay transmits data in a co-frequency co-time full duplex manner. Alternatively, operating frequency bands of two adjacent antenna bays of the at least two antenna bays are adjacent frequency bands or are separated by one or two frequency bands, each antenna bay includes at least one receive channel and at least one transmit channel, and each antenna bay transmits data in an asynchronous manner. An angle value between a line connecting center points of any two adjacent antenna bays of the at least two antenna bays and a horizontal line is acute. By using the present invention, isolation between antenna bays of the antenna array is increased.

    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.
