Abstract: The present disclosure relates to coaxial dual-band antennas. One example antenna includes a waveguide tube, a ring groove, and a high frequency feed. The waveguide tube has a tubular structure and is configured to transmit a first electromagnetic wave. The ring groove whose opening direction is the same as an output direction of the first electromagnetic wave is on a wall of the waveguide tube. A frequency of the first electromagnetic wave is lower than a frequency of an electromagnetic wave transmitted by the high frequency feed. The high frequency feed is located in the waveguide tube and has a same axis with the waveguide tube.

Abstract: Embodiments provide a frequency selective surface (FSS). The FSS includes uniformly arranged FSS units. Each FSS unit includes a dielectric slab, a cross-shaped metal patch, and N square-ring metal patches. The cross-shaped metal patch is adhered to a first surface of the dielectric slab, and divides the first surface of the dielectric slab into four parts. Each part has a same size and a same quantity of the square-ring metal patches. The N square-ring metal patches are adhered to the first surface of the dielectric slab, and are arranged uniformly, and N is a positive integer power of 4. Lengths of the cross-shaped metal patch in two mutually perpendicular directions are equal, and both a length in each direction and a width of a gap between adjacent patches need to meet a specific condition.

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.
