The procedure yields the complex-valued excitations to achieve a minimum-maximum sidelobe level given a specified pointing direction and mainlobe width, as well as prescribed field nulls. All inter-element coupling effects coming from complex radiating structures used as array elements are inherently taken into account. Numerical results are presented for arrays of dielectric resonator antennas.}, keywords = {Antenna arrays, arbitrary planar arrays, complex-valued excitations, dielectric resonator antennas, dielectric resonators, electromagnetic coupling, electromagnetic wave scattering, generalised scattering matrix analysis, inter-element coupling effects, linear programming, minimum sidelobe level array, minimum-maximum sidelobe level, pattern synthesis technique, prescribed nulls}, issn = {0013-5194}, doi = {10.1049/el:20092008}, url = {http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=\&arnumber=4733076}, author = {J C{\'o}rcoles and Gonz{\'a}lez, M A and Zapata, J} }
