Abstract
An apparatus for estimating a direction of arrival includes an antenna, a beamforming network, and an evaluator. The antenna is configured to receive signals, is circularly polarized, and includes a plurality of different radiation patterns. The beamforming network is configured to provide based on signals received by the antenna decomposed signals that are received by associated radiation patterns of the plurality of radiation patterns. The evaluator is configured to estimate the direction of arrival based on the decomposed signals and based on information describing signal receiving characteristics of the antenna. The invention also refers to a corresponding method.
