Abstract: An antenna includes a first element, a second element, and a reactance-adjustable component. The first element receives an excitation current through an electrical connection to an antenna feeder, and the second element generates an induced current through electromagnetic induction of the first element. The reactance-adjustable component is disposed at an end of the first element close to a reference plane, and/or the reactance-adjustable component is disposed at an end of the second element close to a reference plane. The reference plane uses a connection point between the first element and the antenna feeder as an origin point and is perpendicular to an axial direction of the first element. The reactance-adjustable component has an adjustable reactance value and is configured to adjust a phase difference between an excitation current and an induced current, where the phase difference has an association relationship with a target angle of radiation of the antenna.

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: 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: This application provides an antenna system and a wireless device, and pertains to the field of communications technologies. In this application, a decoupling resonator is connected to a first antenna, and a resonance frequency of the decoupling resonator is within an operating frequency band of a second antenna, so that the decoupling resonator can resonate within the operating frequency band of the second antenna. The decoupling resonator reduces coupling between the first antenna and the second antenna, and isolation between the first antenna and the second antenna is improved.
