相位陣列天線

Phased array antennas are an essential component in the growth of 5G wireless systems because they provide more direct beamforming characteristics and steering than traditional single antennas. 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.

用戶可以通過使用內建的幾何建模或導入CAD圖檔來設置相位陣列天線系統。 VSim 可用於分析天線特性,並在不同介電質條件下獲得波束成形的解,甚至在使用Tech-X的動態電漿求解器獲得的電漿中求解。

使用者可以基於以下因素觀察輻射模式變化:

  • 幾何配置
  • 元素之間的相對位移
  • 元素之間的激發振幅
  • 元素之間的激發相位
  • 基於單個元素的模式耦合

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.

 

With VSimEM, users can set up antennas with different radiation patterns, frequencies, or polarizations within the same simulation, making it ideal for modeling MIMO antennas.
