“…As a matter of fact, most of the a-priori methods are based on the definition of a Global Cost Function (GCF) consisting of a weighted combination of cost functions relevant to each target [1]. Notwithstanding, it is not always easy to correctly translate the priorities among targets in the GCF, even when using a smart fuzzy logic approach as in [8], and multiple runs of the algorithm are usually required to tune the used GCF.…”

Abstract-In this paper we focus on multi-objective optimization in electromagnetic problems with given priorities among the targets. The approach proposed in this paper is able to build a proper cost function capable to correctly implementing the design criteria and their priorities avoiding the evaluation of the Pareto front of the solutions, which is a very time consuming task required in the classic a-posteriori methods. The resulting function, named Quantized Lexicographic Weighted Sum (QLWS), can be used as cost function in a very large class of electromagnetic problems. In this paper we demonstrate its usefulness in two common situations in antenna array design: the synthesis of a sparse linear array and a sparse isophoric ring array.

Abstract:The aim of this paper is to present the experimental characterization of a reconfigurable parasitic patch antenna for Multiple Input Multiple Output (MIMO) applications. The proposed antenna is able to work with two different polarizations, providing separate control of the antenna pattern of each of the two polarizations. Both numerical and experimental results show the adaptive capabilities of the antenna, proving its effectiveness for MIMO applications.

“…Accordingly, in the last years several approaches for the design of antennas providing diversity functions in operating frequency [1,2,6], polarization [3][4][5] and radiation pattern [1,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] have been proposed. Among them, antennas able to modify their radiation pattern while preserving the working frequency and polarization are key components for improving the performance and security of MIMO (Multiple-InputMultiple-Output) architectures [5,9].…”
