Embodiment Construction

[0021] Such as figure 1 As shown, the optimization method of the present invention first uses the multi-dimensional uniform sampling algorithm to design the initial sample; then partially replaces the electromagnetic simulation solution with the Kriging model; then uses the population composition and screening method to balance the breadth and depth of the search to obtain the antenna optimization model.

[0022] Among them, the initial sample includes selecting n optimized parameters in the antenna structure, determining the parameter space D according to the value range of each parameter, using the LHS-MDU algorithm to generate 10n initial samples in D, and performing simulation on the initial samples to obtain 10n×m Electromagnetic response, calculate the fitness, store the initial sample and its electromagnetic response in the database, and construct the initial Kriging model.

[0023] The population composition includes setting the population number Np=10n in the optimiza...

Abstract

The invention discloses a method for rapidly optimizing simulation design of an antenna. The optimization method is characterized by comprising the steps of firstly, designing an initial sample through a multidimensional uniform sampling algorithm; then replacing electromagnetic simulation with a Kriging model part for solution; then balancing searching breadth and depth through a population composing and screening method, so that an optimized model of the antenna is obtained. By the adoption of the method, under the same optimization setting, compared with existing algorithms, the number of simulation times required for reaching the optimization target is reduced by 70% or above, and antenna simulation optimization design efficiency is improved.

Description

technical field [0001] The invention relates to the field of optimization design of electromagnetic structures, in particular to a fast optimization method for antenna simulation design. Background technique [0002] In recent years, in order to meet the complex requirements of various communication systems in terms of bandwidth, polarization, directivity, shape, and size, the antenna structure has become increasingly complex, and the degree of freedom in design has been continuously improved. Therefore, the antenna design process has become a high-dimensional multi-objective process. the optimization process. Existing design methods are generally based on mature antennas, through surface current, electromagnetic mode or impedance analysis, local adjustment of the structure to obtain new performance, and complete parameter optimization by examining the impact of sensitive parameters on performance one by one. This method relies on the designer's experience and can handle lo...
