Sažetak:
Antenna radiation pattern is a two- or three-dimensional diagram of the antenna gain (as a function of azimuth and elevation) provided by the antenna manufacturer. It refers to the far field of the single antenna situated in free space, without any obstacles. In the near field, this pattern is generally not applicable or should be considered with caution, even for the single antenna in free space. In the real life, antenna is backed by a pole, wall or other structure, and often surrounded by other conductive objects in the immediate vicinity. These objects tend to distort the antenna radiation pattern. Since the electromagnetic field calculation for the coverage or radiation hazard analysis depends on the three-dimensional antenna gain, this effect should be taken into account. Our previous work ([1-3]) on this issue suggests the use of "installation uncertainty" that should be added to the field calculation. The amount of this quantity depends on the installation geometry and could be calculated numerically for a specific situation. This paper shows the results of numerical calculations for some typical antenna installation geometries.
