Abstract

A dual band antenna for a so-called mobile telephone comprises a supply conductor (5) which is connected to the circuits of the mobile telephone. The supply conductor (5) is galvanically connected to a first antenna section (8) which is approximately planar and has a number of loop-shaped conductor members (10). The conductor members (10) are galvanically connected in series and are disposed in sequence after one another in the longitudinal direction (14) of the antenna. The conductor member (10) which is located most distally from the supply conductor (5) is galvanically connected to a second antenna section (9). The second antenna section (9) is substantially straight and essentially parallel with the longitudinal direction (14) of the antenna.
