This paper focus on studying techniques that allow optimization of a communication system by analyzing the patterns of antenna configurations and digital modulations. Antenna design methods are discussed, taking into account parameters such as the number of elements in arrays and modulation types. Computer simulations are made with the use of LTE system simulation and antenna packages freely available...
In this work, a novel synthesis technique for the design of linear uniformly fed sparse arrays has been presented. Such method, based on a fully analytical procedure, is able to mimic a given array factor mask without using computationally demanding optimization algorithms. As an example, an array of 51 antennas having aperture L*max = 24.5 λo has been designed in order to synthesize a very complex...
Beamforming capabilities of ESPAR antenna structures have attracted considerable attention in recent literature. In this letter, we consider a different beamforming approach, presenting an efficient optimization algorithm which enables such antennas to create desired transmit radiation patterns in real time, rather than patterns aiming at signal to interference ratio maximization. The proposed algorithm...
