1. A wide band directional antenna, comprising:
a transmission line,
at least three elements which are at least partially aligned in a stack configuration, electrically isolated from each other, the at least three elements including:
a lower element comprising at least one reflector circuit,
a middle element comprising at least one dipole circuit connected to the transmission line, and
an upper element comprising at least one director circuit,
wherein the at least one dipole circuit comprises at least one first pair of conductive elements, 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, to form a major dipole,
a first element of the at least one first pair of conductive elements and a first element of the at least one second pair of electrically isolated conductive elements at least partially overlapping one another, and
a second element of the at least one first pair of conductive elements and a second element of the at least one second pair of electrically isolated conductive elements at least partially overlapping one another.
