Abstract: An antenna includes a first helical arm and a second helical arm. The first helical arm is wound clockwise along a longitudinal direction of an axis of the antenna, and the second helical arm is wound counterclockwise along the longitudinal direction of the axis of the antenna. The second helical arm and the first helical arm form at least one intersecting point, a first feeding point is disposed on the first helical arm, a second feeding point is disposed on the second helical arm, the first feeding point and the second feeding point are two points symmetrical relative to the axis of the antenna, and any intersecting point of the at least one intersecting point further forms a third feeding point, where the first feeding point and the second feeding point are connected to a first feeding port, and the third feeding point is connected to a second feeding port.

Abstract: An embodiment of the present invention discloses a waveguide filter, which includes a first waveguide at an upper layer and a second waveguide at a lower layer. The first waveguide and the second waveguide are isolated from each other by a metal isolation layer. The first waveguide forms a first resonant cavity. The second waveguide forms a second resonant cavity. The first resonant cavity and the second resonant cavity overlap each other. A coupling slot is disposed at the metal isolation layer in an overlapping area.

Abstract: This application provides an antenna assembly, including two antenna boards that are placed in a stacked manner. Polarization manners of the two antenna boards are perpendicular to each other, and the two antenna boards are configured to separate a received electromagnetic wave into a horizontal polarization component and a vertical polarization component. A bias voltage is applied to a liquid crystal dielectric layer in the two antenna boards to change ratios of reflection power to transmission power of the two antenna boards, to change a ratio of reflection power of the two polarization components that are obtained through separation, and implement linear polarization at different angles after vector synthesis is performed on the two polarization components. In this way, receive power of an antenna is increased.
