Abstract
An antenna device for a hand-portable radio communication unit including a casing with a ground plane means cooperating with the antenna device. The antenna device comprises first and second radiating elements (1a, 1b) being tuned to different resonant frequencies and having a common feed point (1c). The radiating elements (1a, 1b) are disposed in a compact arrangement on a support means (3) so as to be confined entirely in the casing (2).
