An antenna combination intended for small mobile stations, in which there are two antennas provided with feeds of their own. One antenna is primarily for the lower band and the other for the higher band. The radiator of the former antenna, or the first radiator (310), comprises a relatively narrow first portion (311) starting from its feed point (FP1) and then a planar portion (312), which is wide in respect of the first portion. In addition, the first portion comprises, for improving the matching and bandwidth of the antenna, a conductor pattern with a strip conductor (313, 314) which extends from the starting end of the first portion between the tail end of the planar portion and the second radiator, the strip conductor being provided with a ground coupling. The radiators are apart from the circuit board (PCB) of a radio device. An adequate capability is achieved for the parts of an antenna structure for the lower and higher band without matching circuits on the circuit board of a radio device, which circuits require space and are sensitive. |
