Abstract

An antenna device for several frequency bands comprises a radiating element (15) which, in rough outline, is designed as a planar helix. The radiating element (15) is disposed on a carrier (4) of insulating material and radiates in at least two discrete and separate frequency bands. The radiating element (15) further includes a number of substantially straight conductor portions (16, 16', 16", ..., 17, 17', 17", ...). The straight conductor portions (16, 16', 16", ..., 17, 17', 17", ...) are galvanically united with one another by the intermediary of curved or angular conductor portions (18, 18', 18"). Together, the different conductor portions (16, 16', 16", ..., 17, 17', 17", ..., 18, 18', 18") form an angular helix.
