Abstract

In this paper, the simulation and experimental studies of SAR distribution in a bio-medium situated very close to a rectangular dielectric resonator antenna (RDRA) in C-band of microwave frequencies are reported. The simulation study has been carried out using CST Microwave Studio simulation software. The experimental distribution has been obtained using two 50Ω L-shaped and straight probes and Agilent make 3 Hz-50 GHz spectrum analyzer. The experimental results for SAR distribution are compared with simulated results.
