Directional antenna system comprising of an array of a dipole and additional closely coupled the parasitic elements (generally a reflector and one or more directors). The dipole in the array is driven and the other element, usually 5% longer, efficiently operates as a reflector.

The other parasitic elements shorter than the dipole might be added in front of the dipole and are termed to as the directors.
