Abstract

To address the complexity of full-array antenna simulation models and reduce computational demands, this study introduces an innovative design and simulation method for phased array antennas based on metasurfaces with composite periodic structures. This approach harnesses the arithmetic phase differences between array elements to engineer a phased array capable of beam scanning, thereby simplifying the complex initial model into a streamlined basic unit cell model with periodic boundary conditions, which significantly enhances the efficiency and speed of full-array antenna design and analysis. In this research, we constructed two types of phased arrays using microstrip patch antennas with composite periodic structures: a comprehensive full-array model and a periodic model. Finite element simulation results have confirmed a high level of consistency in antenna gain between these two models. The simulation and analysis method presented in this paper not only effectively reduces the complexity of the simulation model but also conserves computational resources without sacrificing the accuracy of the results, providing an effective computational strategy for the design and simulation analysis of complex full-array antennas.
