在本文中，我们提出了最新的进展设计的SKALA，对数周期天线选择的SKA-low仪器。经过几年的发展，SKALA已经升级，以满足苛刻的SKA-low要求。天线的机械升级是至关重要的，以满足可部署性，环境规格等的要求。EM模拟是了解所有这些升级对望远镜性能的影响的关键。我们讨论了权衡和建议的解决方案，以保持或超过与SKALA-1实现的性能。
In this paper we present the recent advances on the design of SKALA, the log-periodic antenna chosen for the SKA-low instrument. After several years of development, SKALA has being upgraded to meet the demanding SKA-low requirements. Mechanical upgrades on the antenna were critical in order to meet the requirements for deployability, environmental specifications, etc. EM simulations are key to the understanding of the effects on the telescope performance of all of these upgrades. We discuss the trade offs and the solutions proposed to maintain or exceed the performance achieved with SKALA-1.
