Modified Dual Segment Rectangular Dielectric Resonator Antenna Terminated in a Bio-Medium
Abstract: In this paper, the simulation studies of the radiation characteristics of modified dual segment rectangular dielectric resonator antenna (DSRDRA) in free space and in presence of bio-medium alongwith the absorbed power distribution in a homogenous bio-medium (muscle layer) in direct contact with the proposed antenna are reported at different WiMAX band frequencies. The specific absorption rate (SAR) distributions in muscle layer for different antenna-to-muscle layer spacings are also presented at resonant frequency of antenna in WiMAX bands. The results of return loss, input VSWR and radiation characteristics of proposed antenna in bio-medium are also compared with results in free space. The simulation study has been carried out using CST Microwave Studio software.
