Abstract: A measuring system for determining phase differences of antenna element signals of antenna elements of an antenna array under test is provided. The measuring system comprises a signal generating means, which is configured to provide a measuring signal to the antenna array under test over the air and receiving means configured to measure the antenna element signals, resulting from receiving the measuring signal by the antenna elements of the antenna array under test and determine the phase difference of the antenna element signals.

Abstract: A measuring system for determining a beamforming quality of an antenna array signal of an antenna array of a device under test. The measuring system comprises a measuring device configured to receive an antenna array signal, and to measure the antenna array signal and to determine a beamforming signal quality thereof. The antenna array signal is wirelessly transmitted to the receiver by the antenna array of a device under test. The measuring system further comprises a positioning unit configured to position the device under test in successive predefined orientations. The measuring device is configured to receive and measure the antenna array signal successively in each of the predefined orientations.

Abstract: A system for measuring or characterizing a multi-element antenna having at least two antenna elements comprises a vector network analyzer with at least two input/output ports. Each input/output port of the vector network analyzer is connected to one antenna element of the multi-element antenna. The vector network analyzer has generator means for generating waves at each of its input/output ports, which are coherent to each other.

Abstract: An interior trim part with an airbag device has an airbag module (1) with a pot-shaped housing (11) for accommodating an airbag (12) which is attached at the protruding end of a firing passage (24) to a dimensionally stable support (2). An opening section (23) for the deployment of the airbag is predetermined in the support (2) by means of tear lines (21) and/or hinge lines. The problem arises of preventing, by means of a simple measure, the opening section (23) from tearing off during the deployment of the airbag (12). For this purpose, it is proposed that a first section (41) of a retaining band (4) is attached to the opening section (23), said retaining band running within the firing passage (24) as far as the base of the airbag module (1) and being fastened there.
