Abstract :
Antennas located at the outside of a human body are studied through FDTD simulations. Low-profile antennas are designed using electromagnetic bandgap (EBG) structure and are positioned to radiate power to the outside and inside of a human body. By changing the distance between the antennas and a biological tissue, the return loss variations of the antennas are observed and the radiation efficiencies and specific absorption ratio (SAR) are calculated.
