The pattern function is used to describe the radiation patterns of antennas. In the system definition windows, each transmitter and receiver of both victim and interfering links has an "Antenna Patterns Identification" panel, which allows you to define antenna parameters. The positioning of the antennas and its pointing convention in a scenario is described in ‎ANNEX 11:.
