使用GPU加速和粒子群优化算法优化天线设计

本研究考虑了使用XFdtd为无人值守地面传感器设计宽带天线的示例。 为了在干燥和潮湿地面条件下都获得可接受的性能,我们使用了粒子群优化算法(PSO)。 XStream GPU加速和MPI + GPU技术使这种复杂的仿真策略成为可能,完成了数百代多次优化,以收敛于最佳值。

Conformal Antenna Array Design Using XFdtd Simulation Software

Conformal Antenna Array Design Using XFdtd Simulation Software

Array modeling is a multistep process that often includes several revisions until the design goal is met. The Mobile Base Station Designer in XF’s XTend Script Library helps to speed up this design process. XStreamGPU Acceleration rapidly simulates the array using the actual antenna model to ensure the final design meets the design criteria. This presentation demonstrates how to design a conformal antenna array on a curved surface.

Time-Saving Technologies to Simulate and Tune Conformal Antennas for Modern Mobile Devices

The bottlenecks for simulation tools used for antenna design are typically in two areas: project setup and simulation speed.  By reducing the time spent in these two areas, RF engineers have more time to design their antennas.  Remcom’s XFdtd reduces these bottlenecks in several ways, including parameterization, scripting, advanced meshing techniques, and GPU implementation of the computational algorithm.
