High gain printed dipole array with reflectors and directors

An array of eight printed dipole elements with directors and reflectors has been realized, we obtain very good results in terms of adaptation, radiation, side lobe level and back radiations. The simplicity of its realization is an asset to minimize the global cost of the strucutre. We can use this antenna to make a switchable circular antenna by duplicating it on a cylindrical structure. A 4x1 array with asymetricalpower distribution has been realized, in order to create a switchable antenna. Many measurement results will come in a few months.
