Description
Enter the name of the radiation pattern.
Select the type of antenna to start with from the drop- down list. You can choose from None, Dipole, Yagi, Patch, or Parabolic.
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°.
Modify Radiation Pattern
Click <Modify> on the Radiation Pattern Repository dialog box to modify a custom radiation pattern. The Modify Radiation Pattern dialog box appears.
