An antenna coupling device is disclosed for connecting substantially inductively first antenna to a second antenna, whereat the antenna coupling device comprises as loop antenna (4) with two poles (15. 16). The loop antenna (4) is arranged to surround the first antenna and is connected to the second antenna via both of its poles (15, 16). Such an antenna coupling device connected via a cable (5) to an external antenna by the action of threading the antenna coupling device onto a helical antenna (2) of a hand-portable telephone (1) is used inside a vehicle for improving transmission and reception conditions for the handportable telephone (1).
