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.

Abstract

The invention discloses a method for machining a perforated structure form luneberg lens and relates to the technical field of manufacturing of a perforated luneberg lens antenna. The method mainly comprises the following steps of designing parameters, such as the caliber, a layer number along the radial direction, the number of each layer of holes, and the shape of the holes, of the perforated structure luneberg lens, through electromagnetic software simulation; according to the designed parameters, adopting large 3D (three-dimensional) software to model the perforated structure form luneberg lens antenna; guiding the built model into 3D printing equipment, and preparing the perforated structure form luneberg lens by 3D printing technology. The method is high in machining precision, high in efficiency and low in cost, is not affected by a gap layer, and is particularly suitable for machining the whole perforated luneberg lens.

Description

technical field [0001] The invention relates to the technical field of manufacture of perforated Lunberg lens antennas, in particular to a high-precision, high-efficiency and low-cost antenna processing method, which is suitable for the integral manufacture of Lunberg lenses in the form of perforated 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 developed by leaps and bounds. Among them, the Lunberg lens antenna has received extensive attention due to its wide scanning range, wide frequency band, simple feeding network, and low cost. The Lumberg lens antenna is a spherically symmetric dielectric retardation lens whose refractive index changes with the radius. It can converge the incident plane wave to the focal point at the radial position of the sphere. Every point on the lens ...
