    摘要： An antenna arrangement including at least two antenna functions arranged to cover a certain angular sector, each antenna function comprising a corresponding antenna port. The antenna arrangement is configured to perform: a first direction of arrival (DOA) estimation for a transmitting device at a first frequency, and a second DOA estimation for the transmitting device at a second frequency, wherein the second frequency has a larger magnitude than the first frequency, and wherein at least one second frequency grating lobe is apparent in the angular sector at the second frequency. The antenna arrangement is configured to: distinguish the at least one second frequency grating lobe from a second frequency main lobe using results from the first DOA estimation, and identify a pointing direction of the second frequency main lobe as a resulting DOA estimation. Related methods are also described.
