    摘要： Embodiments of this application disclose a multibeam antenna. The multibeam antenna can implement beam coverage in at least two directions by feeding through at only one end. There is no need to dispose a complex feeding network, thereby facilitating miniaturization of the multibeam antenna. The multibeam antenna in the embodiments of this application includes: a substrate, an antenna element, a first guiding apparatus, and a second guiding apparatus. The antenna element, the first guiding apparatus, and the second guiding apparatus are disposed on the substrate. The antenna element includes a first pole and a second pole. The first pole is configured to receive a feeding signal. The second pole is grounded. The first guiding apparatus is configured to enable a first beam generated by the antenna element to radiate in a first direction. The second guiding apparatus is configured to enable a second beam generated by the antenna element to radiate in a second direction. A phase center of the antenna element is located at an intersecting point of a first axis and a second axis. The first axis passes through a phase center of the first guiding apparatus and is parallel to the first direction. The second axis passes through a phase center of the second guiding apparatus and is parallel to the second direction.

    摘要： This application relates to the field of antenna technologies, and in particular, to a reconfigurable antenna and a communications device. The reconfigurable antenna includes a first antenna and a second antenna. The first antenna is an omnidirectional antenna, and the second antenna surrounds the first antenna. The second antenna includes a plurality of antenna element groups. Each antenna element group includes a transmission cable, a switch, a first antenna element, and a second antenna element. The transmission cable is connected to the first antenna element and the second antenna element. The transmission cable is connected to a feedpoint. The switch is connected to a first point and a second point on the transmission cable. A sum of a length from an end of the first antenna element to a connection point between the first antenna element and a first end of the transmission cable, a length from the first end of the transmission cable to the first point on the transmission cable, a length from a second end of the transmission cable to the second point on the transmission cable, and a length from an end of the second antenna element to a connection point between the second antenna element and the second end of the transmission cable is slightly greater than 1/2λ 1 , and λ 1 is a wavelength of an electromagnetic wave on an operating frequency of the first antenna. The reconfigurable antenna in this application can be switched among an omnidirectional mode, a directional mode, and a high-density mode.

    摘要： This application provides a lens, a lens antenna, a remote radio unit RRU, and a base station. The lens includes a substrate layer and a metal layer, where at least one surface of the substrate layer is a concave surface or a convex surface; the metal layer exists on the at least one surface of the substrate layer; the metal layer includes a metal part and a hollow-out part, and the metal part or the hollow-out part is presented by using a graphics array; the graphics array includes a plurality of first rings, the first ring includes a plurality of graphic units, and a larger ring encircles a smaller ring in the plurality of first rings; and at least one of two adjacent first intervals, and sizes and rotation angles of the plurality of graphic units included in two adjacent first rings are different, where the first interval is an interval between the two adjacent first rings. In the technical solutions provided in this application, a phase shift amount of a transmitted electromagnetic wave is generated by using the metal layer, so that a phase shift amount generated by changing a thickness of the substrate layer can be reduced, the thickness of the substrate layer can be reduced, and a thickness of the lens can be further reduced.
