Abstract: Antenna elements (101, 102) used for multi-band antenna dual polarization include: four radiating elements (201), a balun element configured to feed power to the radiating elements (201), and a fastening plate (202) configured to fasten the balun element. The balun element includes two dielectric plates (203). Two signal transmission units (301), one feeding unit (401), and two filtering units (402) are printed on each dielectric plate (203). An LC resonant energy storage structure is constructed on the balun element by using the filtering units (402), and decoupling on a specific frequency band can be implemented by adjusting the filtering unit (402). Therefore, even if the antenna elements (101, 102) are applied to a scenario in which elements on different frequency bands work collaboratively, radiating elements (201) on different frequency bands are not coupled electromagnetically and strongly when the radiating elements are arranged closely.

Abstract: An antenna subarray and a base station antenna are disclosed. The antenna subarray includes a reflection plate, a plurality of radiation surfaces, and a ground plate of the plurality of radiation surfaces. The ground plate is vertically disposed on the reflection plate, and includes an integrated bottom end structure and a plurality of branch structures. The bottom end structure is connected to the reflection plate, and a top end of a branch structure is connected to a radiation surface. A feeder layer is disposed on a side of the ground plate, and a dielectric layer is spaced between the ground plate and the feeder layer. A first polarized feeder and a second polarized feeder are disposed on the feeder layer. The ground plate may have both a “ground” function of a polarized feeder and a “ground” function of a balun. The first polarized feeder and the second polarized feeder can implement both a function of a polarized feeder of the radiation surface and a function of a balun feeder.

Abstract: Embodiments of the present invention provide a multi-frequency communications antenna and a base station. The multi-frequency communications antenna includes at least one low-frequency array, at least one high-frequency array, at least one circuit board disposed corresponding to the high-frequency array, and a reflection panel, where a filtering component configured to decouple filtering is disposed on the circuit board, a first end of the filtering component is electrically connected to the high-frequency array, and a second end of the filtering component is electrically connected to a signal ground layer of the circuit board. The filtering component configured to decouple filtering that is shown in this embodiment is disposed on the circuit board, which causes a small damage to an array radiation environment.
