Phased Array Antennas

With their ability to provide more direct beamforming characteristics and steering than traditional single antennas, phased array antennas are an important component in the growth of 5G wireless systems. Engineers working to improve phased array antenna systems need simulation software that provides timely and accurate results. As an FDTD simulation tool, VSim can simulate multiple frequencies simultaneously, and only VSim implements a unique algorithm specialized for efficient far-field calculations.

Users can set up phased array antenna systems by using built-in geometries or importing CAD files.  VSim can be used to analyze antenna features and obtain beamforming solutions under different conditions with dielectrics, and even plasma with Tech-X’s kinetic plasma solver.

Users can observe radiation pattern changes based on:

  • Geometry configuration
  • Relative displacement between elements
  • Excitation amplitude between elements
  • Excitation phase between elements
  • Coupling based on the pattern of individual elements
With VSim, users can set up antennas with different radiation patterns, frequencies, or polarizations within the same simulation, making it ideal for modeling MIMO antennas.
VSim users can perfect their antenna designs by measuring coupling effects between array elements and reflections, as well as calculate S-parameters for each array element and create beamforming graphs. To optimize design configurations, users can analyze performance results based on key elements such as: HPBW & FNBW, directivity, side-lobe levels, and more.
