Abstract: A dielectric lens, where 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, computer numerical control (CNC) machining, or a three dimensional (3D) printing process technology, and the units may be assembled through gluing, welding, structural clamping, or a coupling printed through 3D printing. When the dielectric lens is applied to a multi-beam antenna, a system capacity of a communications system can be increased. In addition, a thickness of the lens is reduced using the multi-beam antenna.

Abstract: The present disclosure relates to telecommunication, and in particular, to a base station Radio Frequency (RF) duplexer, an RF module, and an RF system. A base station RF apparatus provided herein includes: an enclosure, an intermediate RF processing unit, and a duplexer. The enclosure is located on the duplexer; the intermediate RF processing unit is located inside a cavity enclosed by the enclosure and the duplexer, or on the duplexer; a duplexer cavity and a heat dissipation part exist on the surface of the duplexer; the opening of the duplexer cavity is opposite to or against the enclosure; the heat dissipation part is designed to dissipate heat of the intermediate RF processing unit; and the duplexer is integrally molded. The foregoing technical solution requires no external fasteners, reduces the time of production and assembly. In addition, waterproof design and shielding design are not required, and thus improves the reliability.
