Abstract (en)
The present invention relates to an antenna device for a portable radio communication device operable in at least a first high-frequency band and a second low-frequency band. The antenna device comprises: an on-ground radiating element (2) having at least a first port (3) for feeding of the first high-frequency band and a second port (4) for feeding of the second low-frequency band; first selecting means (7) connected to the first port, and second selecting means (8) connected to the second port; the first selecting means is configured to open-end (P1) the first port and the second selecting means is configured to connect the second port to a second matching network (P6, P7, P8) through which the second low-frequency band is fed (10), when the antenna device operates in the second low-frequency band; and the second selecting means is configured to ground (P5) the second port and the first selecting means is configured to connect the first port to a first matching network (P2, P3, P4) through which the first high-frequency band is fed (9), when the antenna device operates in the first high-frequency band.
