  • Patent number: 6118409
    Abstract: In order to inspect at least one antenna branch (A1, A2, . . . An), in particular in a vehicle, a power level to be radiated is initially fed into the antenna branch, after which a power level which is reflected in the antenna branch is sensed. Then, a relationship is formed between the fed-in power level and the reflected power level in order to obtain a quality signal indicating the quality of the antenna branch. This procedure can be carried out successively when there are a plurality of antenna branches, in order to select, as a function of the respective quality signal, that antenna branch at which the reflected power level is lowest. In this way, on the one hand, it is possible to check the matching of the antenna branches while, on the other hand, it is possible to ensure that, for example when specific antenna branches are damaged, it is always possible to find other antenna branches for satisfactory communication.
