摘要： A reconfigurable antenna includes a bottom plate, a vertically polarized high-density antenna, and a controllable reflector. The controllable reflector is located between the bottom plate and the vertically polarized high-density antenna, and a projection of the controllable reflector on the bottom plate is at a center of a projection of the vertically polarized high-density antenna on the bottom plate. The controllable reflector includes a switch, and the switch is configured to enable the controllable reflector to be in an operating state or an off state.

摘要： The application provides an antenna and a communications device, and pertains to the field of antenna technologies. The antenna includes a horizontally polarized antenna and a vertically polarized antenna that are disposed in a superposition manner. The horizontally polarized antenna includes a metal sheet, and the metal sheet can be separately connected to a double-sided parallel strip line in the horizontally polarized antenna and a first conductor of a coaxial cable. A diameter of a maximum inscribed circle of the metal sheet is greater than a line width of the double-sided parallel strip line, and both the metal sheet and the coaxial cable are located on a first side of a substrate. Therefore, the metal sheet can effectively suppress an induced current in the coaxial cable, and impact of the induced current on the vertically polarized antenna can be reduced.

摘要： An antenna for wireless communications includes a horizontal polarization antenna and a vertical polarization antenna that are disposed in a stacked manner. The horizontal polarization antenna includes a radiation element and a double-sided parallel strip line. One end of the double-sided parallel strip line is connected to the radiation element. A length range of the double-sided parallel strip line is 0.58 to 1.35 times a waveguide wavelength of an electromagnetic wave in the double-sided parallel strip line at an operating frequency of the vertical polarization antenna.

摘要： An antenna has a reflector and an active element. The reflector includes a multi-segment metal structure having a length within a first value range. The multi-segment metal structure includes a first metal structure connected to a second metal structure. A PIN diode is disposed on the first metal structure. The first metal structure is parallel to a polarization direction of the active element. The second metal structure is perpendicular to the first metal structure.

摘要： An antenna assembly includes N elements, a feeding network, and a printed circuit board (PCB). N is an integer greater than or equal to 3. The N elements and the feeding network are located on the PCB. The N elements are all connected to the feeding network, each element has a radial part, the radial part of each element points to an antenna phase center, and a length of the radial part of each element is greater than a sum of lengths of other non-radial parts.
