Conformal antennas arrays radiation synthesis using immunity tactic

Abstract

Purpose -The purpose of this paper is to introduce to scientific community a new optimization technique and its application to the radiation synthesis case. Design/methodology/approach -The immunity tactic is a new powerful optimization tool inspired by immune system. It was used with success to achieve the conformal antenna radiation synthesis in an acceptable processing time.Findings -Radiation synthesis of conformal antenna arrays based on immunity tactic generates very good results compared with other optimization methods. The comparison is very satisfactory as regards accuracy and processing time.Research limitations/implications -The improvement of convergence and accuracy will be done certainly by use of other variants of the technique or combination with others. Originality/value -The paper exposes with details a new optimization technique based on immune system and its behavior. The results, for the special case of conformal antenna arrays radiation synthesis, are very satisfactory and very encouraging. The impact of the new technique will be, without doubt, positive on optimization field.

Linear annular antennas array design by evolutionary algorithms: A comparative study

“…In [14], the author uses the linear programming method in the design of antenna patterns with prescribed nulls and other constraints, an improved version of particle swarm optimization was used by Deng [15] to minimizing sidelobe levels and facilitating null placements of nonlinear antenna arrays. In [16] another version of particle swarm optimization method called unified particle swarm optimization with random ternary variables was presented and applied to antenna array synthesis, the design of conformal antennas arrays is optimized using immunity tactic is given in [17]. Recently RAVI [18] applied the differential evolution algorithm for the synthesis of phased array antenna for side lobe level reduction.…”
