The patch antides are thin metal plates on the dielectric substrate and are widely used from smartphones to satellites in compact electronics. One of the most difficult stages in their production is the selection of the shape and geometry of the elements to provide the necessary electromagnetic properties. This process requires thousands of recurrence and strong calculations.
So far, stochastic methods have been used for tasks that simulate natural processes, such as genetic algorithms. However, Russian scientists offered a different approach: Instead of choosing parameters from scratch, they started with an entire plate in which the elements that change the characteristics of the antenna were cut by step.
The new algorithm is based on dual coding and using the so -Called attorney model. This is a simplified copy of the main task that saves resources, predicts promising solutions and only controls if necessary. This approach sharply reduces the load on the information processing power.
The method was tested on three types of antennaes and showed a significant decrease in the number of repetition compared to classical algorithms. In addition, it is universal – it can be used for both home devices and complex aviation or space equipment.
