With the application of the luneberg dielectric lens antenna in the field of mobile communication, higher requirements are put on the manufacturing method of the luneberg dielectric lens. The medium lens antenna has the advantages that the high gain, wide beam, ultralight and other performances of the original medium lens antenna are kept, meanwhile, the manufacturing process of the medium lens is simpler, the operability is stronger, the one-time finished product rate is higher, and the medium lens antenna is more suitable for mass production.
The traditional luneberg ball antenna is mainly manufactured by two processes of punching and foaming, the process is time-consuming and tedious, and the product quality is too heavy. The efficiency of lens antennas is very low; the dielectric constant of the material obtained by the traditional foaming method is difficult to exceed 1.4, and the density of the material is inevitably large to increase the weight. The dielectric constant of which is difficult to control precisely.
The Matsine luneberg ball is a lighter artificial medium luneberg ball, but the manufacturing process is complex and the product percent of pass is low. Moreover, the Matsine luneberg antenna with high antenna gain has the same width of vertical plane beam as the traditional mobile communication base station antenna, the vertical coverage is difficult to expand, and even if a complex vertical beam downtilt mechanism is provided, the near-distance and the far-distance can not be simultaneously covered.
