  • Patent number: 10151783
    Abstract: An apparatus and a method for determining an antenna characteristic of an antenna under test in free space is disclosed. Measurement results of a transmitted power of a measurement signal transmitted between the reference antenna and an antenna under test are detected, wherein detecting takes place in the frequency domain. The detected measurement results are transformed into the time domain and a time-domain filter is applied to the measurement results converted into the time domain. A filter width of the time-domain filter is determined in dependence on a spatial distance between the reference antenna and the antenna under test. Measurement result portions that result due to a multipath propagation of the measurement signal between the reference antenna and the antenna under test are reduced or removed.
    Type: Grant
