摘要：In this paper, a wideband dual segment cylindrical dielectric resonator antenna (CDRA) is proposed for 5 GHz WLAN/WiMAX band. The simulation results for the radiation characteristics of the proposed antenna and the absorbed power distribution in a homogenous bio-medium (muscle layer) in direct contact with the proposed CDRA are reported at different frequencies. The specific absorption rate (SAR) distribution in muscle layer for antenna-to-bio-medium separation of 200 mm is also determined at the antenna resonant frequency of 6.238 GHz. The input characteristics of CDRA are compared with those of single segment CDRA of same size and different material dielectric constants. The simulation study has been carried out using CST Microwave Studio software.
