ABSTRACT:
An antenna, in particular a mobile radio antenna, operates in at least two frequency bands. Two or more dipole antenna elements are provided and are arranged in front of a reflector, which transmit and receive in two different frequency bands. The distance between the antenna element structure, the antenna elements or the antenna element top of at least one dipole antenna element for the higher frequency band is at a distance from the reflector plane which corresponds to at least 75% and at most 150% of the distance between an antenna element structure. An antenna element or an antenna element top of at least one dipole antenna element for the lower frequency band and the reflector plane, and/or the distance between the antenna element structure, the antenna elements or the antenna element top of at least one dipole antenna element for the higher frequency band is at a distance from the reflector plane which is greater than 0.4λ and is preferably less than 2λ with respect to the mid-frequency of the antenna element for the higher frequency.
