Antenna Properties

The antenna performance is modelled using a radiation pattern. You can choose a radiation pattern by clicking in the Radiation pattern list.

Visualyse Coordinate provides a number of standard patterns that have been defined and approved by the ITU. These patterns define the antenna gain as a function of off-axis angle. You can select one of these from the list.

Most of the standard patterns also require D/ as an input. However, some patterns depend on other parameters for example beamwidth, efficiency or peak gain.

These parameters are all related and you can specify the antenna with at least two parameters. Some Radiation patterns assume values for a parameter –e.g. efficiency or diameter and therefore in practice you may have one or two parameters that define your pattern.

Under the ‘I know the’ list, you should select the parameter or the pair of parameters that you know and then enter the values in the fields that appear.
