Synthesis of Thinned Concentric Ring Array with Dipole Radiators Using Firefly Algorithm
نویسنده
چکیده
The application of new metaheuristic approach, Firefly algorithm, for the thinning of large multiple Concentric Circular dipole arrays is presented. A nine-ring Uniform Circular antenna array with central element feeding is considered. To analyze the effect of thinning, optimization is carried out with and without pre fixing the percentage value of thinning. The performance of the array in terms of sidelobe level and beam width is discussed in four cases. The numerically simulated patterns are obtained and compared with those of concentric circular isotropic arrays.

Design of a Fully Digital Controlled Recon- Figurable Switched Beam Concentric Ring Array Antenna Using Firefly and Particle Swarm Optimization Algorithm
Reconfigurable antenna arrays are often capable of radiating multiple patterns by modifying the excitation phases of the elements. In this paper a method based on Firefly Algorithm (FA) has been proposed to obtain dual radiation pattern from a concentric ring array of isotropic elements, by finding out two different combinations of states for the switches, which are assumed to be connected with...

In this paper, circular and hexagonal array geometries for smart antenna applications are compared. Uniform circular (UCA) and hexagonal arrays (UHA) with 18 half-wave dipole elements are examined; also planar (2 concentric rings of radiators) uniform circular (PUCA) and hexagonal arrays (PUHA) are considered. The effect of rotating the outer ring of the PUCA is studied. In our analysis, the me...
