Antenna Settings
Several antenna-related settings can be configured to allow for optimal scenario simulation:
antenna gain pattern, lever arm, and elevation mask.
To configure these settings, navigate to:

3.5.8.1
Antenna model
The
antenna gain pattern
can be specified for each scenario, using a set of pre- defined
antenna models
, or by utilizing a user-specified file. The built-in antenna models assume an
omni-directional gain pattern where the maximum gain is to be found towards the zenith.
The pre-defined antenna models are:
Zero model
: Isotropic antenna with a gain of 0 dBic towards all directions. This is the
default.
Patch
: Gain pattern approximates
TOKO DAK
Series patch antenna with maximum gain
+5 dBic. Size of the patch is 25 x 25 mm and ground plane 70 x 70 mm.
Helix
: Gain pattern approximates
Sarantel SL1200 (GeoHelix-P2)
antenna pattern with
maximum gain -2.8 dBic. This is a small helix antenna designed to be embedded in
handheld devices e.g. mobile phones. See http://www.sarantel.com for details.
Cardioid
: Gain pattern 1+sin (elevation) with maximum gain +3 dBic.
