Abstract: A wide band directional antenna includes three elements which are partially aligned, electrically isolated from each other, of which a lower element includes at least one reflector circuit, a middle element comprises at least one dipole circuit connected to a transmission line, and an upper element includes a director circuit, wherein the dipole circuit includes at least one first pair of conductive elements, suitable for forming a minor dipole connected to the transmission line, and at least one second pair of electrically isolated conductive elements, excited with capacitive effect by the minor dipole, in such a way as to form a major dipole.
