Multiband telecommunication antenna

A multiband radio antenna, in particular for use in cellular telecommunications, including several first, several second and several third radiating elements which operate in three respective different frecquency bands,

• wherein said antenna has a structure which is periodic along a longitudinal axis, and wherein, in each module of a plurality of modules of said structure, a first radiating element is placed at a center of a quadrilateral, two adjoining vertices of which are each occupied by one of said second radiating elements and the other two vertices of which are each occupied by one of said third radiating elements;
• wherein respective radiating elements are aligned in three rows which are parallel to said longitudinal axis of said antenna, and which correspond to said respective different frequency bands,
• said antenna including respective radiating elements which operate in the DCS frequency band from 1 710 to 1 880 MHz, the GSM frequency band from 870 to 960 MHz and the UMTS frequency band from 1 900 to 2 170 MHz;
• and
• wherein each module includes a GSM radiating element, a first pair of UMTS radiating elements, and a second pair of DCS radiating elements, and said first and second pairs of radiating elements define an approximate rectangle at a center of which said GSM radiating element is placed.
