Как моделировать антенны COMSOL Multiphysics®

In this video, we show you how to model a dipole antenna in the COMSOL Multiphysics® software. After watching this video, you will have a solid foundation for creating models of more complex antenna geometries, as the process for building different antenna models is essentially the same. We start by building the antenna geometry; adding material properties; and applying boundary conditions, such as for the impedance, scattering, and lumped port feed. After setting up the model, we automatically mesh it using physics-controlled meshing based on the wavelength and solve for a specific frequency. Several results are extracted from the solution, including the electric and magnetic fields, 2D and 3D far fields, S-parameters, and surface losses.
