[0056] In the prior art, the Poisson characteristics of the material are usually used to perform numerical prediction on the deformed flexible antenna structure, and then software simulation test is performed to simulate the antenna deformation process, so as to determine the deformation resistance of the flexible antenna.

[0057] The present application provides a flexible antenna performance determination method and device, terminal equipment and storage medium, which can solve the above problems by generating a deformation simulation model of the to-be-tested flexible antenna under different deformation variables, and realize the determination of the deformation resistance of the flexible antenna.

[0058] In order to illustrate the technical solutions of the present application, the following specific embodiments are described.

[0059] Referring to Figure 1 , a flowchart of a flexible antenna performance determination method provided by an embodiment of the present application is shown. As Figure 1 shown, the flexible antenna performance determination method can include the following steps:

[0060] Step S101, generating a three-dimensional simulation model of the flexible antenna to be tested according to attribute parameters of the flexible antenna to be tested.

[0061] In the embodiments of the present application, the attribute parameters include structure information, material information and stress-strain parameters of the flexible antenna to be tested. The generating of the three-dimensional simulation model of the flexible antenna to be tested according to the attribute parameters of the flexible antenna to be tested includes:

[0062] An initial three-dimensional model is built in combination with a mechanical simulation system.

[0063] The structure information, material information and stress-strain parameters of the flexible antenna to be tested are imported into the initial three-dimensional model to generate the three-dimensional simulation model of the flexible antenna to be tested.

[0064] In a possible implementation, the mechanical simulation system can be an Ansys mechanical platform, the initial three-dimensional model can be an initial three-dimensional geometric model, and the material information can be material attributes including flexible material parameters.

[0065] Exemplarily, first, a simulation module of the flexible antenna to be tested and an initial three-dimensional geometric model are established in the Ansys mechanical platform. Specifically, after a preliminary antenna design is completed, a three-dimensional geometric model of the flexible antenna is constructed in the simulation module according to structure information and material information of the flexible antenna, and a tensile structure model is imported, wherein the tensile structure includes transverse tensile, biaxial tensile and bending deformation, etc. The tensile structure model can also be a human body model. Then, material attributes are given to the initial three-dimensional geometric model to generate the three-dimensional simulation model of the flexible antenna to be tested, wherein for the dielectric substrate part of the flexible material to be tested, the flexible material parameters are fitted by a hyperelastic model.

[0066] Step S102, generating a deformation simulation model of the flexible antenna to be tested under different deformation variables in combination with the three-dimensional simulation model of the flexible antenna to be tested and preset deformation parameters.

[0067] In the embodiments of the present application, the deformation parameters include tensile variable parameters under different deformation variables and arch bridge bending radius parameters. The generating of the deformation simulation model of the flexible antenna to be tested under different deformation variables in combination with the three-dimensional simulation model of the flexible antenna to be tested and preset deformation parameters includes:

[0068] The deformation simulation model of the flexible antenna to be tested under different deformation variables is generated in combination with the three-dimensional simulation model of the flexible antenna to be tested, the tensile variable parameters under different deformation variables and the arch bridge bending radius parameters.

[0069] In a possible implementation, the deformation parameter can be a displacement condition, including a tensile variable parameter under different deformation variables and an arch bridge bending radius parameter, specifically, a horizontal tensile variable parameter and an arch bridge bending radius parameter, and when the imported tensile structure model is a human body model, the displacement condition further includes a displacement application parameter of the to-be-tested flexible antenna on the human body. When the flexible antenna is attached to the human body, the physical change of the structure thereof is very complex, and the existing technology cannot simulate the result when the antenna is conformal to the human body based on the Poisson property of the material as a theoretical basis. The mechanical change will cause deviation of the simulation result. By constructing a human body model and related parameters, complex physical changes of the flexible antenna when attached to the human body can be realized, and the simulation effect of the non-uniform multi-directional deformation on the human body is good.

[0070] The embodiment can realize real and accurate physical simulation of antenna deformation, especially simulation of performance changes of a flexible antenna on a human body. The antenna deformation realized based on the physical simulation software in the mechanical simulation system can complete multiple complex deformations at the same time, and especially simulate the result of deformation of the flexible antenna on the human body. The deformation test of the antenna conformability has good simulation.

[0071] In a possible implementation, before the deformation simulation model of the to-be-tested flexible antenna under different deformation variables is generated, simulation settings need to be performed, including formulating corresponding step settings to match appropriate operation time and operation result.

[0072] In the embodiment of the application, before the deformation simulation model of the to-be-tested flexible antenna under different deformation variables is generated by combining the three-dimensional simulation model of the to-be-tested flexible antenna and the preset deformation parameter, the method further includes:

[0073] According to the deformation parameter, the three-dimensional simulation model of the to-be-tested flexible antenna is subjected to grid division processing.

[0074] In the embodiment of the application, before the deformation simulation model of the to-be-tested flexible antenna under different deformation variables is generated by combining the three-dimensional simulation model of the to-be-tested flexible antenna and the preset deformation parameter, the method further includes:

[0075] Exemplarily, referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , after the above settings are completed, a deformation example diagram of the flexible antenna under different tensile application scenarios can be obtained on the Ansys mechanical platform.

[0076] In a possible implementation, the deformation simulation model of the to-be-tested flexible antenna under different deformation variables is generated according to a three-dimensional simulation model of the to-be-tested flexible antenna, flexible material parameters, deformation parameters, and simulation settings, wherein the deformation simulation model under different deformation variables can be a model of different percentage deformation degrees, that is, a result model at each percentage deformation in the deformation process of the to-be-tested flexible antenna.

[0077] In step S103, the deformation resistance performance of the to-be-tested flexible antenna is determined according to the deformation simulation model under each deformation variable.

[0078] In the embodiment of the present application, the deformation resistance performance of the to-be-tested flexible antenna is determined according to the deformation simulation model under each deformation variable, including:

[0079] According to the deformation simulation model under each deformation variable, the deformation degree information and the stress condition information of the to-be-tested flexible antenna under different deformation variables are determined.

[0080] According to the deformation degree information and the stress condition information of the to-be-tested flexible antenna under different deformation variables, the deformation resistance performance of the to-be-tested flexible antenna is determined.

[0081] In a possible implementation, the stress-strain curve of the mechanical simulation antenna after deformation can be determined according to the deformation simulation model of the to-be-tested flexible antenna under different deformation variables, and the deformation degree and the stress condition of each step stage can be further obtained, the result analysis of the overall structure deformation resistance capability of the to-be-tested flexible antenna is obtained, the deformation resistance performance of the to-be-tested flexible antenna is determined, the bending deformation area of the antenna can be effectively analyzed, and the stretchability and bending resistance of the structure are provided for theoretical analysis.

[0082] The embodiment accurately describes the physical characterization in the deformation process of the to-be-tested flexible antenna by using the mechanical simulation system, can effectively avoid the performance test misalignment caused by the deformation result deviation of the to-be-tested flexible antenna, and realizes the simulation and simulation of the mechanical stretching and human surface deformation performance of the flexible antenna.

[0083] The above embodiment of the present application discloses a flexible antenna performance determination method, which first generates a three-dimensional simulation model of a to-be-tested flexible antenna according to attribute parameters of the to-be-tested flexible antenna, then generates a deformation simulation model of the to-be-tested flexible antenna under different deformation variables in combination with the three-dimensional simulation model of the to-be-tested flexible antenna and preset deformation parameters, and finally determines the deformation resistance performance of the to-be-tested flexible antenna according to the deformation simulation model under each deformation variable. The embodiment discards the traditional method of simulating antenna deformation by using the Poisson characteristics of materials, generates a deformation simulation model of the to-be-tested flexible antenna under different deformation variables by a physical simulation method, accurately and in detail describes the physical characterization of the flexible antenna in the deformation process, and can effectively evaluate the deformation resistance capability of the antenna structure.

[0084] Referring to Figure 6 , a flowchart of a flexible antenna performance determination method is shown. The flexible antenna performance also includes electromagnetic wave radiation performance. The radiation performance of the flexible antenna is highly affected by the degree of structural deformation. Scattering parameters (S parameters) and other data are commonly used to describe the electromagnetic wave radiation performance of the flexible antenna in this state, which describes the frequency domain characteristics of the transmission channel. Using scattering parameters, a to-be-tested flexible antenna can be regarded as a "black box" with input and corresponding output, so that system modeling can be performed without having to worry about the complex details of the actual structure. Analyzing the deformation process of the flexible antenna and the electromagnetic wave radiation performance after deformation helps to optimize the structure of the flexible antenna and improve the performance of the flexible antenna.

[0085] As Figure 6 shown, the flexible antenna performance determination method can include the following steps:

[0086] Step S601, generating a three-dimensional simulation model of a to-be-tested flexible antenna according to attribute parameters of the to-be-tested flexible antenna.

[0087] Step S602, generating a deformation simulation model of the to-be-tested flexible antenna under different deformation variables in combination with the three-dimensional simulation model of the to-be-tested flexible antenna and preset deformation parameters.

[0088] Step S603, determining the deformation resistance performance of the to-be-tested flexible antenna according to the deformation simulation model under each deformation variable.

[0089] The steps S601-S603 of this embodiment are the same as the steps S101-S103 of the foregoing embodiment, and can be mutually referred to. This embodiment will not be described again here.

[0090] Step 604, importing the deformation simulation model under each deformation variable into an electromagnetic simulation system to generate an initial electromagnetic model.

[0091] In a possible implementation, after determining the deformation resistance performance of the flexible antenna under each deformation variable according to the deformation simulation model under the deformation variable, simulation results under each deformation variable, i.e., each step, are added, and a corresponding stl model file is derived for radiation performance testing of an electromagnetic simulation system. The electromagnetic simulation system can be loaded with CST electromagnetic simulation software. In the process of simulation stretching, model edge breakage may occur, and therefore, the edge breakage part in the deformation simulation model under each deformation variable needs to be repaired first. Specifically, the derived stl file is imported into a three-dimensional entity direct modeling module, the damaged model surface that may exist is repaired, the deformation simulation model is split into different parts to facilitate subsequent assignment of different materials, the deformation simulation model is converted into an entity model, and the deformation simulation model is exported in stp format. The three-dimensional entity direct modeling module can be a Spaceclaim module, and Spaceclaim is a three-dimensional entity direct modeling software. Then, the entity model is imported into the CST electromagnetic simulation software. The physical and electromagnetic distribution changes of the antenna deformation are simulated by using Ansys software and CST software, which can effectively avoid the influence of objective factors generated by physical testing, greatly reduce the time and labor cost, and the simulation process is simple and fast, and the deformation resistance performance of the flexible antenna can be quickly and effectively evaluated.

[0092] Exemplarily, the initial electromagnetic model of the deformation simulation model after stretching in the X direction and the deformation simulation model after deformation on the human arm model is taken as an example, and is shown in FIGS. 1 and 2. Figure 7 and Figure 8

[0093] In step 605, an electromagnetic simulation model of the flexible antenna under different deformation variables is generated in combination with the initial electromagnetic model and preset electromagnetic physical parameters. The scattering parameters of the flexible antenna under test can be determined through the electromagnetic simulation model.

[0094] In the embodiment of the present application, the electromagnetic physical parameters include the relative permittivity and relative permeability of the flexible antenna under test. The combination of the initial electromagnetic model and the preset electromagnetic physical parameters to generate the electromagnetic simulation model of the flexible antenna under different deformation variables includes:

[0095] The initial electromagnetic model, the relative permittivity and the relative permeability of the flexible antenna under test are combined to generate the electromagnetic simulation model of the flexible antenna under different deformation variables.

[0096] ​In a possible implementation, the electromagnetic physical parameter can be a material attribute. After importing the entity model into the CST electromagnetic simulation software, the material attribute is assigned to the entity model, and the corresponding material is added to the structure and the human body model based on the selected flexible antenna design. The material attribute includes the relative permittivity and the relative permeability.

[0097] In a possible implementation, between generating the electromagnetic simulation models of the to-be-tested flexible antenna at different deformation amounts, the electromagnetic field boundary condition, the working frequency, the feed port, and the field monitor of the required frequency are set in the CST electromagnetic simulation software based on the electromagnetic performance estimation of the to-be-tested flexible antenna, so as to complete the test of the radiation performance of the deformed to-be-tested flexible antenna in the CST electromagnetic simulation software.

[0098] Exemplarily, the comparison chart of the scattering parameters of the flexible antenna at different stretching degrees after the antenna is stretched in the X direction is as shown in FIG. 6. Figure 9 The scattering parameter chart of the flexible antenna after deformation on the human arm model is as shown in FIG. 7. Figure 10

[0099] In a possible implementation, the electromagnetic simulation model can also determine the electromagnetic field distribution. Based on the deformation degree information and the stress condition information of the deformed flexible antenna obtained by the mechanical simulation, and the electromagnetic field distribution chart of the deformed flexible antenna model obtained by the electromagnetic simulation, the change rules of the electric field and the magnetic field of the antenna at different deformation degrees and in different deformation directions can be specifically summarized and analyzed, so that the specific structure can be effectively adjusted in parameters.

[0100] In step 606, the electromagnetic wave radiation performance of the to-be-tested flexible antenna is determined according to the scattering parameter of the to-be-tested flexible antenna.

[0101] Specifically, the result analysis of the radiation capability of the deformed flexible antenna is obtained according to the scattering parameter and other data of each deformation degree obtained from the electromagnetic simulation result, the performance of the flexible antenna design is effectively evaluated, and the parameter and theoretical guidance for the optimization of the structure design is provided.

[0102] Compared with example one, this example includes the deformation simulation of the flexible antenna in the mechanical simulation system and the performance test of the deformed antenna in the electromagnetic simulation system. In this example, the mechanical structure of the designed flexible antenna is used to establish the three-dimensional simulation model of the to-be-tested flexible antenna in the mechanical simulation system, the physical deformation is applied to obtain the deformation result of the flexible antenna, and the electromagnetic calculation of the deformed antenna is completed in the electromagnetic simulation system, so that the joint simulation of mechanics and electromagnetism is realized.

[0103] ​Compared with the deformation result predicted by the Poisson ratio in the prior art, the embodiment performs real physical simulation on the antenna structure, especially the super-elastic material part, can effectively analyze the bending deformation area of the antenna, and thus obtains more accurate antenna deformation result, and provides theoretical analysis on the stretchability and bending resistance of the structure.

[0104] The embodiment fuses the multi-physical field collaborative operation of the mechanical simulation system and the electromagnetic simulation system, effectively avoids the deviation caused by the inaccurate deformation result on the antenna performance test. The embodiment accurately and detailedly describes the physical representation in the flexible antenna deformation process based on the mechanical simulation system by using the physical simulation method, so as to effectively evaluate the deformation resistance of the antenna structure and the electromagnetic radiation ability after deformation. The embodiment can quickly complete the deformation resistance test of the designed flexible antenna, shortens the flexible antenna development cycle, and saves time and labor cost.
