The known antenna connectors for transmitting RF-signals from an outside antenna to a portable telephone includes a connecting cable (,), one end of which is connected to the outside antenna (,) and the second end which is connected with a circuit (,), which capacitively or inductively transmits the RF-signals from the outside antenna to a main antenna of the telephone. In order to improve the coupling performance said circuit consists of a meander formed loop (,) of conductive material, which loop (,) is arranged on a substrate (,) of non conducting material and in one end (,) is connected with the connecting cable (,). The cable has a screen (,) which is connected with a ground element (,), and couples with the ground plane of the telephone, whereat the meander formed loop is placed beside main antenna (,) when transmitting RF-signals.
