The present invention relates to an antenna arrangement (10) comprising a number of first radiating elements (11) radiating in a first frequency band and a number of second radiating elements (12, 13, 14, 15) radiating in a second frequency band. The first and the second radiating elements are arranged in different planes. The second radiating elements (12, 13, 14, 15) are arranged in relation to the first radiating elements (11) 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 (A10; a10) and the resonant dimension (A10) of the first radiating element is approximately twice the resonant dimension (a10) 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).
L'invention concerne un réseau d'antennes (10) comprenant un certain nombre de premiers éléments rayonnants (11) émettant dans une première bande de fréquences et un certain nombre de seconds éléments rayonnants (12, 13, 14, 15) émettant dans une seconde bande de fréquences. Les premiers et les seconds éléments rayonnants sont disposés dans différents plans. Les seconds éléments rayonnants (12, 13, 14, 15) sont disposés par rapport aux premiers éléments rayonnants (11) de manière que chaque second élément rayonnant chevauche partiellement le premier élément rayonnant correspondant. Chaque élément rayonnant a au moins une dimension résonnante (A¿10?; a¿10?). La dimension résonnante (A¿10?) du premier élément rayonnant équivaut approximativement à deux fois la dimension rayonnante (a¿10?) des seconds éléments rayonnants et les seconds éléments émettent à une fréquence, ou dans une bande de fréquences, correspondant à deux fois environ celle des premiers éléments rayonnants.
