Abstract :
In this paper, the interaction between a printed CPW-fed UWB antenna and a lossy cylinder is theoretically investigated to study the reflection coefficient, radiation characteristics and specific absorption ratio (SAR) over the band. The antenna characteristics for different cases were calculated using the commercially available High-Frequency Structure Simulator (HFSSreg). The printed CPW-fed UWB antenna was first fabricated and tested in free space environment. Here, the influence of the body-worn printed UWB antenna when located close to a lossy body is investigated
