Antenna arrangements having radiating elements radiating at different frequencies

An antenna arrangement comprising a conductive ground plane, a number of first radiating elements radiating at a first frequency or in a first frequency band and a number of second radiating elements radiating at a second frequency or in a second frequency band, for each first radiating element a group of second radiating elements being arranged,

• wherein the first and the second radiating elements respectively are arranged in different planes, the second radiating elements in a group being symmetrically arranged, at least in pairs, in relation to the corresponding first radiating element in such a way that each second radiating element partly overlaps the corresponding first radiating element and wherein each radiating element has at least one effective resonant dimension, the effective resonant dimension of the first radiating element(s) being substantially twice that of the effective resonant dimensions of the second radiating elements so that the second radiating elements radiate at a frequency or in a frequency band which is approximately twice that of the first radiating element(s).
