Design, analysis, application and experimental assessment of algorithms for the synthesis of maximally sparse, planar, non-superdirective and steerable arrays
… planar, maximally sparse, steerable and non-superdirective array antennas by means of convex optimization algorithms and testing their performances on an existing array to assess its far field performances in terms of requirements ful- filment. The reason behind the choice of such topic is …

MIMO Communication Capacity: Antenna Coupling and Precoding for Incoherent Detection
… the antennas are placed close together. Because superdirective behavior is difficult to achieve in practice, this work formulates an approach for limiting the impact of superdirectivity by introducing finite ohmic loss into the capacity expressions. Results show that even a small amount of ohmic …

Superdirectivity and the Application of Complementary Split Ring Resonators in Directivity Enhancement of Millimeter-Wave Antennas
… and bandwidth requirements. Initially, a superdirective antenna is developed using a new approach. Complementary split ring resonators are used to enhance directivity and manipulate the complex current distribution over a printed dipole. Systemic design approaches are presented using …
