EM Radiation Analysis of Electrical Dipole in Close Vicinity of Dissipative Object
A phenomenon of electromagnetic wave propagation produced by a GSM mobile phone antenna at the operating frequency 950 MHz, placed in close vicinity of a dissipative object has been investigated and measured. The model (phantom head) of a dissipative object representing and simulating electromagnetic properties of human head tissue in the GSM frequency band has been made. Dielectric properties of the phantom head have been measured. A GSM mobile phone antenna and GSM base station antenna were approximated with dipole antennas and adjusted to GSM frequency band. Radiation patterns and antenna efficiency of the GSM mobile phone antenna settled near the phantom head for vertical and horizontal polarization of the antennas have been measured and recorded on three specific frequencies inside the GSM frequency band.
