Abstract :
Many wireless communication devices are used with their antennas in close proximity of the human head. This results in changes in the antenna characteristics that affect the communications performance and in the deposition of microwave energy in the user´s head that for some devices may be in excess of the values allowed by health protection standards. These effects are evaluated using the FDTD method for two new types of antennas and the results are compared to those for a generic monopole handset
