In the case of the arrangement according to the invention, a connecting terminal (2) for the first operating frequency (f1) is connected to a first connection of the antenna (1), and a connecting terminal (3) for the second operating frequency (f2) is connected to a second connection of the antenna (1). The two connections of the antenna (1) are in each case connected, via series tuned circuits which are tuned to the operating frequency (f1 or f2 respectively), to a reference point which is jointly associated with both operating frequencies (f1, f2). The antenna arrangement is tuned by means of reactive elements (6, 7) to the resonant frequency corresponding to the respective operating frequency (f1, f2). In this case, one series resonant circuit in each case represents a short circuit for the tuning elements which are not required, so that the antenna arrangement can be tuned separately for each frequency without the parameters influencing one another. <IMAGE>
