Abstract

What is disclosed is a device for determining a piece of information on a position of a transmitter, comprising an antenna device, a signal processing device and a data processing device. Thus, the antenna device comprises several different directional characteristics, the directional characteristics each relating to at least a set of spatially different receive sensitivities of the antenna device. The antenna device receives signals from the transmitter with different directional characteristics, the signal processing device processing the signals received and establishing a respective amplitude value of a field strength. The data processing device establishes the information on the position of the transmitter based on the directional characteristics and the amplitude values having been established for the associated signals received. Additionally, a corresponding method is disclosed.
