چکیده
This paper presents a model that uses bio-inspired optimization algorithms to control of the mutual coupling (MC) in Multiple-Input Multiple-Output (MIMO) systems. The method promotes an increase channel throughput and reduction distance among array elements, searching values less than half wavelength. A microstrip antenna design, at frequency 26 GHz, is used as prototype for MIMO system testing performance analysis. Genetic Algorithm (GA) optimize, determine physical parameters improve its performance. impedance concept MC. particle swarm (PSO) algorithm optimize reduce between elements. Simulation results show it possible obtain improvement 11.1% throughput, width reduced by 14.5% elements can be 23.7%, considering

Design of Planar Microstrip Antenna Arrays and Mutual Coupling Effects
In patch antennas, characteristics such as high gain, beam scanning, or steering capability are possible only when discrete patch elements are combined to form arrays. The elements of an array may be spatially distributed to form a linear, planar, or volume array. Planar arrays have elements distributed on a plane. Planar array configurations are extensively used in both communication and radar...
متن کاملSubset Selection Based on Bio - Inspired Algorithms
Many feature subset selection algorithms have been proposed and discussed for years. However, the problem of finding the optimal feature subset from full data still remains to be a difficult problem. In this paper, we propose novel methods to find the relevant feature subset by using biologically-inspired algorithms such as Genetic Algorithm and Particle Swarm Optimization. We also propose a va...
متن کاملOptimal Idle Speed Control of a Natural Aspirated Gasoline Engine Using Bio-inspired Meta- heuristic Algorithms
In order to lowering level of emissions of internal combustion engines (ICEs), they should be optimally controlled. However, ICEs operate under numerous operating conditions, which in turn makes it difficult to design controller for such nonlinear systems. In this article, a generalized unique controller for idle speed control under whole loading conditions is designed. In the current study, in...
