Problems solved by technology
However, the positioning and processing of the holes in the mechanical processing method is difficult, and the number of holes is large, there are problems such as deformation and insufficient mechanical strength, and the physical firmness between the sub-components is low.
In addition, this method inevitably needs to be processed in layers along the radial direction, and the gap layer between the layers is inevitable. The gap layer has a huge impact on the electrical performance, which seriously reduces the overall performance of the antenna.
Therefore, the existing Lumber lens antenna processing technology cannot meet its requirements, which seriously restricts its development.

Description
technical field [0001] The invention relates to the technical field of manufacture of Luneburg lens antennas with apertures, in particular to a high-precision, high-efficiency, and low-cost antenna processing method, which is suitable for the overall manufacture of Luneburg lenses with aperture structures. Background technique [0002] With the rapid development of satellite communication technology, radar navigation technology, aerospace communication, telemetry and remote sensing and other technologies, various types of antennas have made great progress. Among them, the Lunberg lens antenna has attracted wide attention because of its wide scanning range, wide frequency range, simple feeding network, and low cost. The Luneberg lens antenna is a spherically symmetric dielectric retardation lens, whose refractive index changes with the radius, and can converge the incident plane wave to the focal point of the spherical diameter position. Every point on the lens surface is a f...
