摘要： The embodiments of the present disclosure belong to the technical field of communications. Disclosed are a metasurface unit and an antenna. The metasurface unit comprises: a metal radiation patch with a notch, an upper-layer dielectric plate, a metal ground layer, and a lower-layer dielectric plate, which are sequentially arranged from top to bottom; and a feed structure, wherein one end of the feed structure is connected to the metal radiation patch, and the other end of the feed structure penetrates a feed through hole and is arranged on a bottom layer of the lower dielectric plate; the feed through hole sequentially penetrates the upper-layer dielectric plate, the metal ground layer, and the lower-layer dielectric plate; and the metal radiation patch may rotate around a central axis, such that different angels of included angles between the notch and the positive direction of an X-axis correspond to different polarization states. Therefore, metasurface units in different polarization states can be obtained by means of adjusting an angle between a notch of a metal radiation patch and the positive direction of an X axis, such that a polarization isolation relationship can be directly achieved between different sub-arrays of an antenna based on a metasurface, thereby reducing crosstalk between sub-flows, and improving data flow transmission efficiency.

摘要： This application discloses an antenna and a base station, where the antenna includes: a reflection plate, a radome, a heat sink, a radiating element, and a transceiver. The reflection plate has a first surface and a second surface opposite to each other, the radome is disposed on the first surface of the reflection plate, and the radome and the first surface form an enclosed first accommodating space. The radiating element is disposed in the first accommodating space, so that the first surface of the reflection plate integrates a radome installation function. The heat sink is fastened to the second surface of the reflection plate, and the heat sink and the second surface form an enclosed electromagnetic shielding space. The transceiver is located in the electromagnetic shielding space, so that the second surface of the reflection plate has an electromagnetic shielding function. In this application, functions and structural features of three conventional components, namely, a reflection plate, an electromagnetic shielding cover, and a radome installation enclosure frame in the antenna are integrated into a component of the reflection plate, so that a quantity of components in the antenna can be reduced, a weight of the antenna can be reduced, height space of the entire antenna can be reduced, and a size of an antenna product can be reduced, reducing costs.

摘要： To provide a wave control medium that can absorb and control wave motion while achieving downsizing and wider bandwidth of a metamaterial and the like.
A wave control medium 5 includes a three-dimensional microstructure having a base 2, a spiral part 3, and a matching element 6 disposed between the base 2 and the spiral part 3, in which the three-dimensional microstructure includes a material selected from any one of a metal, a dielectric, a magnetic body, a semiconductor, and a superconductor, or a combination of a plurality of these materials. The wave control medium 5 can absorb the wave motion by having the matching element 6 disposed between the base 2 and the spiral part 3 to moderate a change in the entire impedance value.
