Abstract
An antenna connector is used having a ground plane in order to connect an outside antenna with the antenna of a portable telephone via a coaxial cable. The electronic coupling is carried out by means of capacitive electronic coupling between an active member of the cable and the permanent antenna of the telephone. In order to increase the capactive electronic coupling between the active member and the antenna, the active member (5, 15) is screened to the sourroundings at least in one direction from the active member. The screening is carried out by means of a metal plate (12) which is galvanicly connected with the ground plane. The electrical length of the plate is a certain fraction of the wave length of the frequency band of the telephone.
