ABSTRACT:
An improved dipole-shaped radiator arrangement is characterized by the following features: a base is disconnected from ground or a ground surface with respect to direct current, or is capacitively coupled to a ground surface; a first dipole or radiator half is electro-galvanically or capacitively fed by a conductor; a second dipole or radiator half is fed via a further feed line in the form of an inner conductor feed; the one end of the first inner conductor section is electrically connected to a matching network; the other end of the third inner conductor section is connected to ground or to the ground surface with respect to direct current.
