Description
Name Enter the name of the radiation pattern.
Start with
Select the type of antenna to start with from the drop-
down list. You can choose from None, Dipole, Yagi, Patch,
or Parabolic.
Max Gain
The maximum gain controls pattern behavior. The Max
Gain value will be the maximum value of the gain values at
each angle or higher. Positive gain adds power to the
transmitting power while negative gain reduces the
transmitting power.
The table in the Define Radiation Pattern dialog box shows gain values at each angle ranging from 0° to 359°. These values in
the table change depending on the antenna type selected in Start With. To create custom radiation patterns, you can modify
the gain values to get the required radiation pattern. The gain value should be between -99 and 99 dBi.
For example, to modify a standard dipole pattern, start with dipole and modify the gain values for the angles where you want
customization.
Click <Interpolate> if you have defined the gain at two different angles, and want Planner to automatically interpolate the
gain for the intermediate angles. For effective interpolation, ensure that the gain value for all the angles between the two
angles is 0°.
