In real life, shading constructive elements (supports, pipes, stems, masts, etc.) are always located near antennae. The change of antenna characteristics caused by changing the position of a barrier in front of its radiation is investigated. The following antenna characteristics were researched: 3D radiation pattern, gain, polarization ellipticity, and magnitude of electromagnetic field in horn antenna. The simulation takes place at frequencies of 10 and 15 GHz, the material of a barrier is made of fiberglass and copper. A comparison is made of how the characteristics of horn antenna vary with frequency, as well as the thickness of barrier and its position.

Key words: horn antenna, electromagnetic wave, electromagnetic field, directional pattern, gain, coefficient of ellipticity, barrier, fiberglass.
