An antenna for a radio communications apparatus, a so-called mobile telephone, operates in two frequency bands and comprises, on the one hand, a helical radiator (11) and, on the other hand, a bar- or rod-shaped radiator (10). The one end (12) of the bar- or rod-shaped radiator (10) is a supply end and its other end (13) is galvanically connected to a first end (14) of the helical radiator (11). The supply end (12) is connected to the circuits of the apparatus. The other end (15) of the helical radiator (11) terminates freely. |
