Electromagnetic Assessment of Tolerances of the Square Kilometre Array Log Periodic Antenna Using Uncertainty Quantification

This work details the results of a so-called uncertainty quantification analysis conducted on the SKALA 4.2 log-periodic antenna, itself the intended production model of the antenna element for the SKA-Low Antenna Array. The antenna is modelled using the high-order Method of Moments software tool ESTEAM while the tolerance analysis is conducted using the Uncertainty Quantification software tool within TICRA Tools. The results of these analyses are presented, and conclusions drawn regarding the antenna model's electromagnetic robustness against geometrical deviations.
