A Method of GSM Antenna Modeling for the Evaluation of the Exposed Field in the Vicinity

Abstract

In this work, a simple, accurate and very efficient method for the evaluation of the field in the vicinity of GSM antennas of the base-station (BS) in urban areas is presented. The method is based on the replacement of the antenna panel with a group of discrete source emitters. Also, a geometrical approximation is used for the evaluation of the environment's influence. The approximate results are compared with the results taken from the use of NARDA SRM 3000 measuring equipment. The presented method could be successfully used for the exposure evaluation of the electromagnetic (EM) field emitted by GSM antennas of the base-station in urban areas.
