Optimal Phased Array Modeling Using Domain Decomposition

From Dimensions of Electronic Design Seminar, 2012: New computational techniques will be introduced for enhancing the modeling capabilities of finite phased antenna arrays. Creating tapered or sparse finite array element configurations is a snap in ANSYS HFSS 15.0. Solve times may be reduced by several orders of magnitude when only a subset of scan vectors is required or sped up significantly for an array desiring full scan information. Pattern accuracy is enhanced with a new numerical absorbing boundary that is effective at all scan angles. Comparisons of finite array DDM and explicit models will be shown. Finally, guidance will be given about optimal hardware/software setup to tackle phased array modeling.
