Abstract

The invention provides a dielectric lens. The dielectric lens is a lenticular lens or ellipsoidal lens with a quasi-elliptical cross-sectional profile. The dielectric lens formed by piling up a numberof unit bodies. Through the permittivity distribution of the unit bodies in the dielectric lens, a quasi-elliptical non-plane wave in the minor axis direction becomes a plane wave through the dielectric lens. The unit bodies of the dielectric lens are prepared by extrusion, injection molding, stamping, CNC machining or a 3D printing technology. The assembly of the unit bodies can be glue joint, welding, structure clamp connection or direct 3D printing. When the dielectric lens is applied to a cleave antenna, the system capacity of a communication system can be improved. Compared with a traditional cylindrical luneberg lens antenna, the cleave antenna has reduced lens thickness.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, relate to a dielectric lens and a split antenna. Background technique [0002] Traditional antennas used in the communications industry, such as figure 1 As shown, it usually consists of three main parts: (1) radome; (2) feed network, reflector and oscillator array; (3) enclosure and module (active). With the substantial increase of the number of users, the current network is facing the problem of tight system capacity. [0003] The split antenna technology is dedicated to improving the system capacity and communication quality of the mobile communication system, and it is a technical solution with good application prospects. A feasible solution is to set an electromagnetic lens in the split antenna to increase the system capacity, and how to design the electromagnetic lens becomes a technical bottleneck. Contents of the invention [0004] An embodiment ...
