摘要：
A quad-band antenna device (10) for a portable radio communication device comprises an electrically conductive radiating element (11) having an electrical length selected to provide resonance in a first set of frequency bands frequency band. The element includes a first elongated section (12, 13, 14) having a first edge (22, 23, 24) and a second section (15) having a second edge (25, 26, 27) and being joined to the first section via an interconnecting section (16), which second edge (15) faces, is displaced from and stretches along the first edge. In this way a gap (G1, G2, G3) is formed between the first and second sections. The dimensions of this gap are selected to provide resonance of the first electrically conductive radiating element in a second set of frequency bands.
