发明名称 Selective antenna activation arrangement
摘要 The arrangement includes several antennas which are connected over a common conductor. A selection signal is fed into the common conductor for selecting the antenna which is to be activated. An evaluation arrangement is provided on the common conductor, which detects the selection signal, and activates the respective antenna, while deactivating all others. The selection signal may specify the required antenna through its frequency or its polarity. A deactivation of an antenna is preferably performed by short-circuiting its connections.
