A three-band antenna is disclosed, intended in particular for cellular telecommunications. The antenna includes radiating elements operating in three frequency bands. UMTS radiating elements are separated by an optimum distance of 0.95&times;&lgr; , where &lgr; represents the average wavelength of the UMTS frequency band. The positioning of the GSM and DCS radiating elements relative to the UMTS radiating elements is fixed so that each radiating element is similarly surrounded by other radiating elements and by partition walls. The structure is periodic along a longitudinal axis. In each module of the structure, a GSM radiating element is placed at the center of a quadrangle, two adjacent vertices of which are each occupied by a DCS radiating element and the other two vertices of which are each occupied by a UMTS radiating element.

Multiband telecommunication antenna

A crossed polarization antenna system including a substantially flat and rectangular reflector and at least one radiating cell carried by the reflector, each cell including at least two first conductor elements assembled tail-to-tail and energized by a first external power supply forming a first dipole. Each radiating cell includes two second conductor elements mounted in exactly the same way as the first elements and energized by a second external power supply forming a second dipole. The conductor elements are V-shape bent elements with the second elements mounted orthogonally to the first elements. Applications include mobile telephones.
