Beschreibung
Zusammenfassung:	A wide band directional antenna comprises three elements (1, 2, 3) which are partially aligned, electrically isolated from each other, of which a lower element (1) comprises at least one reflector circuit (11), a middle element (2) comprises at least one dipole circuit (21) connected to a transmission line (4), and an upper element (3) comprises a director circuit (31), wherein the dipole circuit (21) comprises at least one first pair of conductive elements (211, 212), suitable for forming a minor dipole (21m) connected to the transmission line (4), and at least one second pair of electrically isolated conductive elements (213, 214), excited with capacitive effect by the minor dipole (21m), in such a way as to form a major dipole (21M).
