Abstract
The invention relates to a mobile terminal antenna system for a first radio application (RA) and a second radio application (RA) the system comprising first radio electronic circuits (REC) for the first radio application (RA), and second radio electronic circuits (REC) for the second radio application (RA). The system also comprises an end-fed antenna () for the first radio application (RA), the end-fed antenna () having an extended shape and being connected to the first radio electronic circuits (REC). The system comprises a dipole antenna () for the second radio application (RA), the dipole antenna () being located near one end of the end-fed antenna () and connected to the second radio electronic circuits (REC). The first radio electronic circuits (REC) are connected to the dipole antenna (), whereby the end-fed antenna () is adapted to be fed, during transmission, against the dipole antenna () by the first radio electronic circuits (REC), whereby the dipole antenna () is adapted to serve as a counterpoise for the end-fed antenna ().
