Abstract (en)
A motor vehicle (A) antenna array (1), of the kind coupled with a substantially flat dielectric system (2), comprising: a first plurality of mutually interconnected electrically conductive elements (3) coupled with a feeding source (4); a second plurality of electrically conductive elements (5), each connected with a pair of conductors of the first plurality of conductive elements (3) to form a composite structure in which one or more substantially polygonal shapes are defined; a feeding element (6) capacitively coupled with the first and second conductive elements (3, 5). The feeding element (6) comprises two or more extraction points of the radiofrequency signals (10, 11) that the antenna array (1) is able to receive. The extraction points (10, 11) are mutually spaced according to a distance substantially equivalent to the half of one of the wavelength related to the radiofrequency signals that said antenna array (1) is able to receive.
