This method, which inherently takes into account every array element pattern as well as all interelement couplings, allows the maximization of the directive or power gain of an arbitrary planar array scanned at whichever direction, subject to constraints on the maximum sidelobe level, the maximum crosspolar level, the minimum aperture illumination efficiency, the setting of null pointing directions or a dynamic range ratio control. Numerical examples of arrays with canonical geometries, composed of microstrip patches or dielectric resonator antennas and covering a wide variety of requirements are presented.}, author = {J C{\'o}rcoles and Gonz{\'a}lez, M A and Rubio, J and Zapata, J} }
