Matched antenna device and a portable radio communication device including a matched antenna device

A matched antenna device (1) for a radio communication device, comprising a matching means (3, 33) and a first antenna element (4), wherein

• the matched antenna device further comprises a flexible dielectric substrate (2) having a first side (21) and a second side (22),
• the matching means (3, 33) comprises a conductive pattern (3), having a first coupling means (31) and a second coupling means (32), and exhibiting inductive and capacitive characteristics, arranged on the first side (21) of the flexible substrate (2)
• a signal ground conductive surface being capacitively coupled to the conductive pattern (3),
• the first coupling means (21) is to be coupled to the circuitry of the radio communication device,
• the first antenna element (4) having a first end and a second end, a feed portion (42) being arranged at the first end, and
• the second coupling means (32) being coupled to the feed portion (42) of the first antenna element (4).
