| 摘要 |
The invention relates to a mobile terminal antenna system for a first radio application (RA 1 ) and a second radio application (RA 2 ) the system comprising first radio electronic circuits (REC 1 ) for the first radio application (RA 1 ), and second radio electronic circuits (REC 2 ) for the second radio application (RA 2 ). The system also comprises an end-fed antenna ( 4 ) for the first radio application (RA 1 ), the end-fed antenna ( 4 ) having an extended shape and being connected to the first radio electronic circuits (REC 1 ). The system comprises a dipole antenna ( 5 ) for the second radio application (RA 2 ), the dipole antenna ( 5 ) being located near one end of the end-fed antenna ( 4 ) and connected to the second radio electronic circuits (REC 2 ). The first radio electronic circuits (REC 1 ) are connected to the dipole antenna ( 5 ), whereby the end-fed antenna ( 4 ) is adapted to be fed, during transmission, against the dipole antenna ( 5 ) by the first radio electronic circuits (REC 1 ), whereby the dipole antenna ( 5 ) is adapted to serve as a counterpoise for the end-fed antenna ( 4 ). |
