摘要： A dielectric lens is provided. The dielectric lens is a cylindrical lens or an ellipsoidal lens whose cross-sectional profile is a quasi-ellipse, and the dielectric lens is formed by piling a plurality of units. Dielectric constant distribution of the units in the dielectric lens enables a non-plane wave in a minor axis direction of the quasi-ellipse to be converted into a plane wave through the dielectric lens. The units of the dielectric lens are prepared through extrusion, injection, molding, CNC machining, or a 3D printing process technology, and the units may be assembled through gluing, welding, structural clamping, or a connection directly printed through 3D printing. When the dielectric lens is applied to a muti-beam antenna, a system capacity of a communications system can be increased. In addition, compared with a conventional cylindrical Luneberg lens antenna, a thickness of the lens is reduced by using the muti-beam antenna.

摘要： Embodiments of this application provides a terminal, and the terminal includes a housing, a front screen, a circuit board, and a power supply. The front screen is disposed on the housing, both the circuit board and the power supply are disposed inside the housing, and the power supply is electrically connected to the circuit board. The front screen includes a toughened glass, a color changing layer, and a display screen that are sequentially stacked. The color changing layer is electrically connected to the circuit board, and is configured to change a color when receiving power supply from the circuit board. The color changing layer is disposed in the front screen, and the color changing layer may change a color when receiving the power supply from the circuit board. The color changing layer is configured only to change a color and cannot display a complex image, and power consumption of the color changing layer is far less than that of the display screen. Therefore, in the terminal provided in the embodiments of this application, the front screen of the terminal can display a target color while consuming less power.
