A dual-frequency band dual-circularly polarized antenna and an antenna system are disclosed. The antenna includes: a first patch, configured to radiate a high-frequency signal; a second patch, including a radiating element and a ground plate, where the radiating element is configured to radiate a low-frequency signal, the ground plate includes a hollow circle, the radiating element is located in the hollow circle of the ground plate, and the radiating element is an open resonant ring; a microstrip feeder; and a first dielectric substrate, configured to place the second patch and the microstrip feeder, where the first patch is above and spaced apart from the second patch, and the second patch is above the microstrip feeder; and an antenna size is between 0.3λ×0.3λ×0.05, and 0.4λ×0.4λ×0.1λ, and λ is a wavelength corresponding to a lowest operating frequency of the antenna.

Dual-frequency band dual-circularly polarized antenna and antenna system

Embodiments of the present invention provide an antenna and a communications device. The antenna of the present invention includes a plurality of antenna units. Each antenna unit includes a plurality of antenna branches and one feed branch. Different antenna branches in a same antenna unit correspond to different frequency bands. At least one antenna unit pair exists in the plurality of antenna units. A distance between two antenna units in each antenna unit pair is less than a first preset distance. Radiation directions of antenna branches in each antenna unit pair that correspond to a same frequency band are different. By means of the present invention, isolation between the antenna units in the antenna can be increased.

Antenna and communications device

This application describes examples of antenna modules, MIMO antennas, and terminals. One example antenna module includes a clearance area, a support, and at least two branches. Each branch is disposed on the support, and a partial projection of the support on a horizontal plane falls within the clearance area, while a projection on the horizontal plane of one end that is of each branch and that is configured to connect to a feed point is outside the clearance area. A projection of a tail end on the horizontal plane is inside the clearance area.
