Biogeography Based Optimization (BBO) is one of the most popular swarm based optimization algorithms that has shown impressive performance over other Evolutionary Algorithms (EAs). A new algorithm is proposed in this paper by making migration variations in BBO, i.e., Graded Emigration Biogeography Based Optimization (GE-BBO) to improve the performance of BBO.Yagi-Uda is one of most widely antenna designs used at Very High Frequency (VHF) and Ultra High Frequency (UHF) due its high gain,low cost and constructional ease. Designing a Yagi-Uda antennainvolves determination of wire-element lengths and spacings in between them. Antenna geometry bear highly complex and nonlinear relationships with antenna gain, impedance and Single Lobe Level(SLL) at a particular frequency of operation. In this paper, a comparative study between BBO and GE-BBO is presented for faster optimization of antenna designs for maximum gain. The best antenna designs are tabulated and average of 10 monte-carlo simulations areplotted for these stochastic algorithms iterative performances in the ending sections.

Abstract


Biogeography Based Optimization (BBO) is one of the most popular swarm based optimization algorithms that has shown impressive performance over other Evolutionary Algorithms (EAs). A new algorithm is proposed in this paper by making migration variations in BBO, i.e., Graded Emigration Biogeography Based Optimization (GE-BBO) to improve the performance of BBO.Yagi-Uda is one of most widely antenna designs used at Very High Frequency (VHF) and Ultra High Frequency (UHF) due its high gain,low cost and constructional ease. Designing a Yagi-Uda antennainvolves determination of wire-element lengths and spacings in between them. Antenna geometry bear highly complex and nonlinear relationships with antenna gain, impedance and Single Lobe Level(SLL) at a particular frequency of operation. In this paper, a comparative study between BBO and GE-BBO is presented for faster optimization of antenna designs for maximum gain. The best antenna designs are tabulated and average of 10 monte-carlo simulations areplotted for these stochastic algorithms iterative performances in the ending sections.
