PCT No. PCT/DE97/01763 Sec. 371 Date Mar. 18, 1999 Sec. 102(e) Date Mar. 18, 1999 PCT Filed Aug. 16, 1997 PCT Pub. No. WO98/12773 PCT Pub. Date Mar. 26, 1998An antenna arrangement which is used for transmitting and receiving radio signals includes a capacitively tunable loop, from which received radio signals can be coupled symmetrically into a receiver stage, and which has a feed-in point, at which a signal to be radiated by the loop can be split into two signals moving in opposite directions to each other and with the same potential. Outcoupling of the received signals from the loop into the receiver stage can take place inductively via a coupling loop, or capactively via outcoupling capacitors, which are connected with the loop.
