本文介绍了SKA-AAlo超宽带天线单元的评估方法。作者将专注于低成本的内部制造和规模化原型的测试，作为转移到射频电波暗室之前的第一步(将解释时间门控等技术)。这既有助于软件验证，也有助于测试构建系统的操作特性(有限金属地平面的影响、来自环境的反射、进给机构的影响等)。
This paper intends to explain an evaluation procedure for ultra-wideband antenna elements for the SKA-AAlo. The authors will focus on low-cost in-house fabrication and testing of scaled prototypes as a first step before moving to RF anechoic chambers (techniques such as time gating will be explained). This is helpful for both software validation and in order to test the operational characteristics of a constructed system (effect of the finite metallic ground plane, reflections from the environment, effect of feeding mechanism, etc.).
