The known antenna connectors for transmitting RF-signals from an outside antenna to a portable telephone includes a connecting cable (8), one end of which is connected to the outside antenna (11) and the second end which is connected with a circuit (4), 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 (4) of conductive material, which loop (4) is arranged on a substrate (5) of non conducting material and in one end (6) is connected with the connecting cable (7). The cable has a screen (10) which is connected with a ground element (9), and couples with the ground plane of the telephone, whereat the meander formed loop is placed beside main antenna (11) when transmitting RF-signals. |
