Design and Optimisation of Dielectric Resonator Antenna array
using PSO Technique

Abstract

This thesis presents design and optimization of Dielectric Resonating Antenna array using PSO technique for wireless application. The designing of the DRA is done in Computer Simulation Technology(CST) microwave studio. The DRA is designed using two disk shaped resonator made from a ceramic material(Ceramic batch #QC1266470) whose dielectric constant is 34.73, FR-4 substrate whose dielectric constant is 4.5 and copper patch. Two dielectric resonators are represented as an array. The resonators are fed by Microstrip transmission line model. The resonating frequency of resonators is 2.4 Ghz. The length of the Microstrip transmission line is ë/4 where ë is the resonator wavelength. The simulation process is done using the same Computer Simulation Technology (CST) Microwave Studio Suite and then the design has been optimized using a Particle Swarm Optimization (PSO) technique to get the desired resonating frequency. The DRA is operating at the frequency bands used for IEEE 802.11b/g Wireless LANs.
