Abstract (en)
An antenna device operable in at least a first lower frequency band and a second higher frequency band comprises a single solid unbranched radiating element (16) having a first (18) and a second (20) opposite end, a first feeding connection (FC1) to the first end (18), a first connection path (P1) between the radiating element and a first frequency band signal handling unit (34), a tuning element (T1) connected to the radiating element for tuning the radiating element for resonance in the first band, a first signal passing and blocking arrangement (24) allowing signals in the first band to pass and blocking signals in the second band, a second connection path (P2) between the radiating element and a second frequency band signal handling unit (32) and a second signal passing and blocking arrangement (28) allowing signals in the second band to pass and blocking signals in the first band. At least one connection path is connected to the first feeding connection.
