EMC sensor for monitoring of EM field safety of mobile networks

Abstract

This paper describes an electromagnetic compatibility sensor for mobile networks monitoring. It consists of wideband fractal dipole antenna, band pass hairpin filter and radio frequency power measurement unit. The antenna is designed as two identical dipoles with fractal geometry. These fractal structures are located on both sides of the substrate. The proposed antenna design with three hexagons for each fractals has good characteristics in wide frequency range from 0,8GHz to 3,6GHz. The presented work is intended to be a key node in a sensor network for radio frequency monitoring.
