Abstract: A multibeam antenna including a substrate, and further includes an antenna element, a first guiding apparatus, and a second guiding apparatus disposed on the substrate. The antenna element includes a first pole configured to receive a feeding signal and a second pole that is grounded. The first guiding apparatus enables a first beam generated by the antenna element to radiate in a first direction, and the second guiding apparatus enables a second beam generated by the antenna element to radiate in a second direction. A phase center of the antenna element is at an intersecting point of a first axis and a second axis, the first axis passing through a phase center of the first guiding apparatus and parallel to the first direction, and the second axis passing through a phase center of the second guiding apparatus and parallel to the second direction.

Abstract: A 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 of antennas and transmission cables in an antenna element group is slightly greater than ½ wavelength (λ1), where λ1 is a wavelength of an electromagnetic wave on an operating frequency of the first antenna.

Abstract: An antenna and a communication device are disclosed. The antenna may be used in an access point. The antenna specifically includes a first conductor sheet and a feed point. The first conductor sheet includes at least two cavities. The at least two cavities are connected through a gap. A circumference of each of the at least two cavities approaches a wavelength corresponding to an operating frequency band of the antenna. The feed point is connected to the gap. The antenna with a simple structure and a small size may generate two beams. Therefore, an access point disposed with the antenna may generate strong wireless signals in two directions, and the wireless signal may cover an adjacent room. In this way, there is no need to deploy an access point in each room, and a quantity of wireless access points to be deployed is reduced.
