IRBBO for Gain Maximization of Fifteen-Element Yagi-Uda Antenna
Biogeography is the study of distribution of biological species, over space and time, among random habitats. Recently introduced Biogeography Based Optimization (BBO) is a technique, where solutions of the problem are termed as habitats. Feature, i.e., Suitability Index Variable (SIV), sharing among various habitats is made to occur with migration operator where as exploration of new SIVs is do...
متن کاملYagi-Uda Antenna Design Optimization for Maximum Gain using different BBO Migration Variants
Biogeography is the study of distribution of biological species, over space and time, among random habitats. Recently developed Biogeography-Based Optimization (BBO) is a technique, where solutions of the problem under consideration are named as habitats; similar to chromosome in Genetic Algorithms (GAs) and particles in Particle Swarm Optimization (PSO). Feature sharing among various habitats,...
متن کاملMicrostrip Yagi-Uda Antenna for 2.45 GHz RFID Handheld Reader
This paper proposes a compact microstrip Yagi-Uda antenna for 2.45 GHz radio frequency identification (RFID) handheld reader applications. The proposed antenna is etched on a piece of FR4 substrate with an overall size of 65 mm × 55 mm ×1.6 mm and consists of a microstrip balun, a dipole, and a director. The ground plane is designed to act as a reflector that contributes to enhancing the antenn...
متن کاملAngular Radiation Patterns of Nanoantennas: an Optical Yagi-uda Antenna
We address experimentally the radiation patterns of quantum dots coupled to optical nanoantennas at specific positions. We show that the emission of the coupled system is determined by a variety of resonant and non-resonant antenna modes both in polarization and angular pattern. The first working optical Yagi-Uda antenna is presented and unidirectional emission is demonstrated for a limited spe...
متن کاملYagi-Uda Antenna for Navigational Aids Using HFSS
In this paper, the ultra high frequency of yagi-uda antenna for navigational has been designed to improve the usable bandwidth by improving the stability of the radiation patterns. The frequency band of ultra high frequency is 300-3000 MHZ. The main aim of this paper is to reduce the loss, improve the gain and also to enhance the efficiency of ultra high frequency yagi-uda antenna for utilizing...
