A MODIFIED FRACTAL RECTANGULAR CURVE DIELECTRIC RESONATOR ANTENNA FOR WIMAX APPLICATION

Abstract

This paper presents the simulation study of a wideband modified fractal rectangular curve iteration-1 (FRC-1) dielectric resonator antenna (DRA) along with conventional FRC DRAs of different iteration levels for WiMAX application. The simulation study has been carried out using CST Microwave Studio software. The design procedure and radiation performance characteristics of modified and conventional FRC DRAs are described and the simulation results for modified FRC-1 DRA are compared with those of a conventional FRC-1 DRA of identical outer dimensions. The simulation results for the material dielectric constant dependent radiation characteristics of both the FRC-1 DRAs are also presented. The results presented here may be useful in designing portable personnel communication device antennas and in analyzing the performance of these antennas for wireless communication.
