Wave field spatial-frequency responses of aperture random antenna

This work is concerned on research electromagnetic field structure generated by three-element aperture random antenna with rectangular configuration. Results of simulation of electromagnetic field structure of described above antenna performed over frequency range 5 kHz…5 GHz are presented. Here observation point is located on the flat platform 20 × 20 m 2 removed from the aperture random antenna on 20 m distance. 3D-surfaces of vector amplitudes for electric E and magnetic H fields and their waive impedance are computed and represented. Also similar 3D-surfaces are obtained and shown for meridional and azimuthal angles that define spatial orientation of vectors E and H over mentioned flat area. Obtained simulation results are initial data for statistical research of electromagnetic field generated by three-element aperture random antenna performed by methods of statistical modeling.
