相控阵天线
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.
用户可以通过使用内置几何图形或导入CAD文件来设置相控阵天线系统。 VSim可用于分析天线特征，并获得不同条件下的电介质的波束成形解决方案，甚至可使用Tech-X的动力学等离子体求解器获得等离子体。
用户可以根据以下情况观察辐射模式的变化。
- 几何配置
- 元素之间的相对位移
- 元素之间的激励振幅
- 元素之间的激励相位
- 基于单个元素模式的耦合
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.
