Abstract

We used the spectrum analyzer with logarithmic - periodic antenna and we adjusted the parameters of spectrum. The purpose of the measurements were to detect whether the cellular mobile antennas are affected by the differentiation of altitude difference, other antennas interference and intermediate obstacles in the particular gym, the 19th Elementary School of Kavala and Faliro Park are of interest due to the everyday high frequency of human activities at those points and if there are any health risks due to exposed frequencies. The frequencies we analyzed were GSM-1800 and GSM-900 but we will focus at 1.850GHz because it is our most interesting frequency in addition of to 950MHz. The specific frequencies were measured, analyzed in five points of interest, three directions and 1m height of ground at each point for finding signals of mobile antennas in the broader area. Cellular mobile antenna signals were detected in specific areas calculated and analyzed the summary of the electromagnetic field strength.
