Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
The detailed description of the invention of the embodiment of the present invention is referred to the flow chart shown in Fig. 1.A kind of 3D prints the method for radio-frequency antenna, specifically includes following steps:
1. printed by 3D and obtain antenna substrate；Specifically include step:
S101: use the model of CAD software design three-dimensional antenna, by the mathematical model that model conversation is printable STL or STP form；
S102: mathematical model is input to 3D printer by antenna substrate, prints antenna substrate after 3D print software Analytic modeling.
3D printer is the high-precision printer based on laser curing molding, and printing precision is 25um/inch.
For the vacuum deposition method that significantly more efficient execution is following, the antenna substrate printed is carried out surface coating process, thus can wipe oil, make smooth surface, it is easy to coat of metal strong bonded.Then, design the mask plate of definite shape according to user's request and cover the antenna substrate surface after coating processes to form the shape of required metal level.
2. by vacuum evaporation by the first metal layer on described antenna substrate plated surface；Specifically include step:
S201: antenna substrate is fixed on the top in vacuum evaporation chamber, is placed in the metallic channel bottom vacuum evaporation chamber by sheet metal；
S202: utilizing molecular pump that the air pressure of vacuum evaporation intracavity is evacuated to 10-5Pa magnitude, heating sheet metal makes it be sublimed into gaseous state.
Under condition of high vacuum degree, the boiling point of object is substantially reduced, and condensation China one-tenth solid is met on the surface that the metal of gaseous state rises to antenna substrate, thus plates the film of thin layer on the exposed surface of antenna substrate.
For the electro-plating method that significantly more efficient execution is following, after vacuum evaporation, evaporation face is carried out surface coating process.
3. on described the first metal layer surface, the second metal level is plated.Particularly as follows:
Utilizing business-like plating means that the antenna substrate plating the first metal layer is carried out the plating of the second metal level, the thickness of the second metal level is much larger than the first metal layer.
The plated surface of antenna substrate becomes after the first metal layer conduct electricity, but the thinner thickness of conductive layer, and even below electromagnetic skin depth, electromagnetic wave can penetrate conductive layer and enter into interlevel dielectrics propagation, reduces the radiation efficiency of antenna.So next utilizing business-like plating means that the sample plating the first metal layer is carried out the plating of the second metal level.The resistivity of the coat of metal is greatly reduced through said process.Protection material can also be coated with further to prevent burning outside the second metal level.
Print the step of radio-frequency antenna based on above-mentioned 3D, the embodiment of the present invention also provides for the manufacture method of a kind of wide-band high gain dual polarization 5G antenna for base station, as in figure 2 it is shown, specifically include step:
