Antenna arrangements having radiating elements radiating at different frequencies
 An antenna arrangement includes a number of first radiating elements radiating in a first frequency band and a number of second radiating elements radiating in a second frequency band. The first and the second radiating elements are arranged in different planes. The second radiating elements are arranged in relation to the first radiating elements in such a way that each second radiating element partly overlaps the corresponding first radiating element. Each radiating element has at least one resonant dimension and the resonant dimension of the first radiating element is approximately twice the resonant dimension of the second radiating elements and the second radiating elements radiate at a frequency, or in a frequency band, which is approximately twice that of the first radiating element(s).
