SKA1-LOW Antenna Design Document


Abstract in English

This document was submitted as part of the SKA Low Frequency Aperture Array Critical Design Review describing the electromagnetic design of the SKA1-LOW antenna that took place between 2013 and 2018. The SKA1 LOW antenna has been developed over the last decade. Since 2011 an antenna of the type Log-Periodic Antenna that is now in its 4th iteration, SKALA4 (SKA Log-periodic Antenna v4), has been developed and was the selected candidate for SKA1-LOW after the Cost Control project efforts of 2017. This document describes the electromagnetic design of the antenna. In the submission for the antenna selection process, a detailed description of the antenna performance can be found. The Field Node Detailed Design Document, also submitted for the SKA LFAA Critical Design Review, presents a detailed design of the mechanics and the LNA as well.
