Abstract
AbstractA comparison of different compliance rules for a small indoor base station antenna is presented at frequencies 1800, 2140, and 2450 MHz using a computational model. The numerical model of the antenna is validated using measurements of free space electric field values in close proximity of the antenna and specific absorption rate in a flat liquid phantom. Losses of the antenna are approximated using the measured radiation efficiency as a scaling factor between the input and output power of the antenna. The compliance distances are then computed using the reference levels for field values and equivalent power density. Obtained values are compared to the basic restriction limit in the upper torso of an anatomically realistic numerical model of a human body. The results show that in this case the reference level of maximum value of equivalent power density gives conservative compliance distances. © 2008 Wiley Periodicals, Inc.
