Electromagnetic fields in the near zone of linear antenna arrays
Keywords:
electromagnetic fields, antenna arrays, near, intermediate and far zones of antenna array, searchlight beam
Abstract
The spatial distributions of the amplitudes and phases of the electric field in the near and intermediate zones for the linear equidistant homogeneous antenna arrays of the isotropic radiators, when the number of radiators and the distance between them have been changing in a wide range, were calculated. It is shown that in the linear antenna arrays, as opposed to the aperture antennas, searchlight beam is not formed in the near zone, and the dependence of the field amplitude on the distance has a downward oscillating character. The amplitudes of the oscillation are increased and disturbed their regular character with increasing the distance between the radiators
