Abstract
A major upgrade of the Pierre Auger Observatory, AugerPrime, whose main purpose is to improve
mass sensitivity studies, will soon be completed. The role of the AugerPrime Radio Detector is
to extend the mass-sensitive measurements to high zenith angles above 65 degrees. The power to
discriminate between different cosmic ray species in the reconstruction depends on the systematic
and statistical uncertainties of the reconstruction algorithm. The main cause of systematic uncertainties of the Radio Detector is the difference between the antenna model and the actual practical
implementation. To determine this uncertainty, we reconstruct CORSIKA/CoREAS Monte Carlo
air shower simulations using an antenna model geometry, slightly modified in various ways. In
addition, we also study the influence of different ground conditions. This work aims to determine
a realistic systematic uncertainty of the electromagnetic energy reconstructed from the Radio
Detector.
