Study of the antenna response for the Radio Neutrino Observatory Greenland (RNO-G) — •Anna Eimer for the RNO-G collaboration — Erlangen Centre for Astroparticle Physics (ECAP), Erwin-Rommel-Str. 1, D-91058 Erlangen

Ultra high energy neutrinos can be detected via radio emission following a neutrino interaction in ice. The long attenuation length of radio signals in ice allows for a much sparser instrumentation than required for optical Cherenkov neutrino telescopes, hence making it possible to survey large volumes. The Radio Neutrino Observatory Greenland (RNO-G) is a project that will eventually consist of 35 stations (7 already deployed) with distances of about 1.25 km between neighbouring stations. Each station consists of 9 log-periodic dipole array (LPDA) antennas about 1.5 m below the ice surface and with up to 100 m deep in-ice strings, equipped with vertically and horizontally polarized dipole antennas.

Understanding the antenna properties and potential interferences between nearby antennas is important to operate the experiment to evaluate the recorded data and reconstruct neutrino properties. In this contribution, first results of lab studies with the RNO-G antennas with emphasis on interferences will be presented.
