This paper presents numerical investigation of the radiation performance from stomach, bladder and heart implanted wireless sources using the Finite-Differences Time-Domain (FDTD). Simulations were performed at the Medical Implanted Communication Systems (MICS) frequency of 402 MHz, using two male and one female digital body phantoms. Azimuthal radiation pattern and radiation efficiency of the implanted wireless sources were calculated. Results have proven that the radiated power is strongly dependant on both; the location of the source, and the body size and composition. Radiation intensity from implanted sources inside the female body was higher than the male body cases, due to smaller female body size and reduced amount of overall lossy human tissues.
