Abstract
A method for determining an angle of arrival and/or a direction of arrival of an electromagnetic wave from a mobile device to a receiving unit, in particular a UWB receiver. The receiving unit includes at least two receiving antennas, For determining the angle of arrival and/or the direction of arrival, a phase difference of arrival between signal responses at the receiving antennas is ascertained. The phase difference of arrival is ascertained at such a location in the signal responses that is still situated in the signal responses prior to a particular midpoint of a first signal path.
