Dynamic Thinning of Antenna Array Using Genetic Algorithm

Thinning is a technique by which the total number of active elements in an antenna array is reduced without causing major degradation in system performance. Dynamic thinning is the process of achieving this under real time conditions. Stochastic techniques have been useful in the design of thinned arrays. However while applying the technique to large 2-D arrays, under changing conditions proble...

Dynamic Thinning of Antenna Array Using Differential Evolution Algorithm

Dynamic thinning is a process by which the total number of active elements in an antenna array is reduced under real time conditions without causing major degradation in system’s performances. This paper suggests a technique by which a thinned antenna array is designed by simple differential evolution(DE) algorithm overcoming the difficulties of large and rugged solution space and slow rate of ...

Thinning of Semi-Elliptical and Quarter-Elliptical Antenna Array Using Genetic Algorithm Optimization

Design of thinned semi-elliptical and quarter-elliptical antenna arrays, with uniform excitation and uniform spacing using genetic algorithm (GA) optimization, is presented in this paper. Thinned arrays produce narrow directive beam without causing major degradation of fully populated antenna arrays. Semi-elliptical array contains antenna elements along half of the elliptical geometry and quart...

Sector Synthesis of Antenna Array Using Genetic Algorithm

This paper introduces a new application of genetic algorithm (GA) in dynamic sector synthesis of antenna array for mobile base transceiver station (BTS). The basic objective is to have narrow beam widths in heavy handoff areas and wider beam widths in areas with low traffic density. By predefining the beam widths and thus the beams of each sector, optimal sectoring can be achieved using GA at d...
