Description
Technical field
The utility model relates to a kind of Waveguide slot array antenna structures suitable for increasing material manufacturing.
Background technique
Waveguide slot array antenna is with compact-sized, thickness is small, light-weight, antenna aperture is high-efficient, easy to accomplish low
The features such as minor lobe, is widely used in radar and communication field.But its internal waveguiding structure is complicated, and dimension precision requirement
Height, the mode for being often used vacuum brazing are processed, but, processing cost height long using the manufacturing cycle of conventional fabrication processes.
Increases material manufacturing technology is not limited by traditional handicraft, and the production cycle can be greatly shortened, reduce manufacturing cost, save material
Material consumption and processing and manufacturing expense are suitble to the small lot trial-production of Waveguide slot array antenna.Common metal increasing material manufacturing method
For selective laser melting molding.
But conventional Waveguide slot array antenna structure is designed for conventional metals processing technology, it is uncomfortable
Conjunction is processed using increases material manufacturing technology.If current metal increases material manufacturing technology is usually using powdering, selectivity layer by layer
The mode of sintering carries out, and the waveguiding structure inside Waveguide slot array antenna is mostly semi-closed structure, is retained in after processing is completed
Metallic particles inside waveguide can not be discharged.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of waveguide gap array day suitable for increasing material manufacturing
Cable architecture should be suitable for the Waveguide slot array antenna structure of increasing material manufacturing while guaranteeing antenna performance, suitable for increasing
Material manufacture.
The utility model is achieved by the following technical programs.
A kind of Waveguide slot array antenna structure suitable for increasing material manufacturing provided by the utility model, including in the same direction side by side
Two cavities；The small structure of hollow out is densely covered on wall between two cavities, the gross area shared by aperture is greater than place wall
The 1/2 of the gross area.
Also small structure is densely covered on other walls of described two cavities, and on the wall between hole shape and two cavities
Aperture it is consistent.
The aperture is with rectangular array or staggered distribution.
The aperture is hexagonal hole or circle hole shape hole.
The hole diameter is 1mm.
Wall thickness between described two cavities is 1mm.
The utility model has the beneficial effects that: can be used for increasing material manufacturing on the premise of ensuring performance, while will produce
50% or more product weight saving has broad application prospects in the aerospace field to weight sensitive.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
A kind of Waveguide slot array antenna structure suitable for increasing material manufacturing as shown in Figure 1, including in the same direction arranged side by side two
A cavity；The small structure of hollow out is densely covered on wall between two cavities, the gross area shared by aperture is greater than the total face of place wall
Long-pending 1/2.
Also small structure is densely covered on other walls of described two cavities, and on the wall between hole shape and two cavities
Aperture it is consistent.
The aperture is with rectangular array or staggered distribution.
The aperture is hexagonal hole or circle hole shape hole.
The hole diameter is 1mm.
Wall thickness between described two cavities is 1mm.
Since increases material manufacturing technology can manufacture various labyrinths, it is possible thereby to which Waveguide slot array antenna is engraved
Sky design guarantees that its internal metallic particles can be smoothly discharged.
Since Waveguide slot array antenna is compact-sized, usually left and right is adjacent or upper and lower overlapping for internal waveguide, to wave
When waveguide slot array antenna carries out hollow design, it need to guarantee the isolation between two adjacent waveguides.
Effective shielding, simulation result can be formed when the size of hole is much smaller than waveguide wavelength according to Small aperture coupling principle
Show the metallic walls of intermediate shared thickness about 1mm or so to guarantee the isolation between waveguide, the shared waveguide of X-band standard waveguide
The array of circular apertures of diameter 1mm is set on wall, and the isolation of two waveguides can reach 70dB or more, i.e. will not mutual shadow between two waveguides
It rings, the size of the hole is guaranteeing it is also ensured that metal powder, hollow out waveguide can be extended to entire Waveguide slot array antenna
Outside metal powder can be smoothly discharged, hole configurations can also be by 50% or more the weight saving of Waveguide slot array antenna.
