Detailed Description
Preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings:
as shown in fig. 1 to 7, the present embodiment provides a method for customizing an antenna with a specific dielectric constant, including the following steps:
step S1, designing a 3D conformal bracket 2 which can be closely attached to the inner surface of the antenna shell 1 according to the inner surface structure of the antenna shell 1;
step S2, performing electromagnetic compatibility simulation test on the 3D conformal bracket 2, the antenna shell 1, the antenna main board and the whole components, and outputting the value range of the dielectric constant of the 3D conformal bracket according to the electromagnetic compatibility simulation test result;
step S3, firing the 3D conformal bracket 2 according to the value range of the dielectric constant, and debugging an antenna for the 3D conformal bracket 2;
step S4, laser the antenna trace onto the 3D conformal bracket 2 through LDS laser forming operation.
In step S1 of this example, the internal surface structure data of the antenna housing 1 is obtained through 3D modeling, but in practical applications, the internal surface structure data of the antenna housing 1 may also be obtained in other manners. And then acquiring the outer surface data of the 3D conformal bracket 2 according to the structure data of the inner surface of the antenna shell 1, so that the outer surface of the 3D conformal bracket 2 is nested in the inner surface of the antenna shell 1, and further the 3D conformal clingy design is realized. The 3D conformal bracket 2 is designed to be in a close-fitting mode in three dimensions with the inner surface of the antenna shell 1, and is the same in shape.
If the optimization design is only realized in space, the performance and the direction of the 3D conformal micro antenna are still limited to a certain extent, and therefore, on the basis of this example, the dielectric constant value range is also selected in a targeted manner according to the environments where the antenna housing 1 and the 3D conformal bracket are located, the 3D conformal bracket is fired according to the dielectric constant value range, the length required by the antenna routing is reduced through a specific dielectric constant, it is ensured that the antenna routing can be fully utilized to the area with the best environment, and the efficiency of the 3D conformal micro antenna is improved to the greatest extent.
More specifically, step S2 in this embodiment preferably includes the following sub-steps:
step S201, selecting an area most beneficial to antenna radiation according to the internal structure and environment of a product, and designing antenna wiring according to research and development experience; the area most beneficial to antenna radiation is also called as an optimal area of a radio frequency environment, and refers to an area which can meet the preset requirements of antenna radiation through simulation, and the preset requirements can be set and adjusted according to actual conditions and requirements; the antenna wiring design is designed by combining the shape and the size of the current 3D conformal bracket 2, and on the basis of meeting the preset requirement of antenna radiation, the length of the antenna wiring can be reasonably reduced so as to facilitate processing and production;
step S202, performing model simulation on the antenna wiring, the 3D conformal support 2, the antenna shell 1, the antenna main board and the whole machine component through electromagnetic compatibility simulation software, and adjusting the dielectric constant value of the 3D conformal support 2 to enable the simulated standing wave to resonate in a frequency band of 2.4G-2.48G, so that the requirement of performing model simulation on the antenna wiring, the 3D conformal support 2, the antenna shell 1, the antenna main board and the whole machine component is considered to be met, and the value range of the dielectric constant is obtained.
In this example, the step S3 is to fire according to the structure of the 3D conformal bracket 2 and the value range of the dielectric constant, debug the antenna trace, and draw and sample the pattern until a preset simulation effect is achieved. And then, radiusing the antenna wiring to the 3D conformal support 2, and carrying out a subsequent LDS radium carving process. The preset simulation effect refers to the simulation effect of the preset antenna efficiency, and can be set and adjusted in a user-defined mode according to actual conditions and requirements. In step S3, after the firing is completed, the product is debugged until the optimal state is obtained, that is, the ideal experience effect of the customer is achieved, and then the next operation is performed to ensure the experience of the product.
It should be noted that, in the step S2 in this example, after the value range of the dielectric constant of the 3D conformal bracket 2 is obtained, it may be preferable to further intercept the value range of the dielectric constant, and select the dielectric constant of the middle section as the final value range of the dielectric constant of the 3D conformal bracket 2. The dielectric constant of the middle section refers to the dielectric constant after the minimum value and the maximum value are removed through a preset rule in the value range of the dielectric constant, and the method has the advantages that on the basis of meeting the requirement of model simulation of the antenna wiring, the 3D conformal support 2, the antenna shell 1, the antenna main board and the whole component, the fluctuation and the span of the value range of the dielectric constant are further reduced, so that the requirement of the whole environment can be adapted more, and the antenna performance of the 3D miniature conformal antenna is more stable and reliable. For example, if the obtained dielectric constant value range is 5 to 11, the dielectric constant of the middle section of 6 to 10 is selected as the final dielectric constant value range of the 3D conformal bracket 2, and the realized antenna effect is better. Of course, in practical application, the interception rule of the value range of the dielectric constant of the 3D conformal bracket 2 can be adjusted and modified according to practical requirements.
In this example, step S3 fires the 3D conformal bracket 2 according to the range of values of the dielectric constant. Since the 3D conformal brackets 2 fired from different raw materials have different dielectric constants, the step S3 in this embodiment is preferably preset with a dielectric constant material correspondence table for passing tests and recording the relationship between the dielectric constants of the various raw materials and the 3D conformal brackets 2 fired therewith. In this example, after the step S2 obtains the value range of the dielectric constant, the step S3 can quickly find the required raw material by querying the dielectric constant material mapping table, so as to fire the 3D conformal bracket 2, and after obtaining the 3D conformal bracket 2 with a specific dielectric constant, the step S3 performs simulation debugging on the product, and after the debugging shows that the 3D conformal bracket 2 is qualified, the step S4 is performed.
In this example, after the antenna trace is radiussed to the 3D conformal bracket 2 in step S4, performance and experience are debugged to the best state through debugging optimization.
In step S5, in the step S5, after the antenna routing is radiussed to the 3D conformal bracket 2 in the step S4, a test is implemented through simulation debugging, and a test result is fed back to the dielectric constant relationship correspondence table, so as to update and store the dielectric constant relationship correspondence table in real time. Because the influence of various factors can be brought in the processing process, each actual parameter of the 3D conformal micro antenna has certain deviation with a theoretical numerical value, so that the embodiment updates and stores the dielectric constant relation corresponding table in real time after the test is qualified, the dielectric constant relation corresponding table is used for dynamically updating or training, continuous optimization and learning training can be further realized, the data can be more accurate and controllable along with the expansion of the data and the time lapse, and a good foundation is provided for the subsequent upgrading and updating of the product.

The clearance area 9 includes clearance positions corresponding to the key structure 4, and may further include other clearance positions, for example, the outer edge of the 3D conformal bracket 2 may include a plurality of arc-shaped clearance positions, as shown in fig. 7, for implementing clearance design of the internal structures of the 3D conformal micro antenna, such as a spacing column, and further improving the internal structure stability of the product by the close-fitting design of the internal structures.
