Antenna normally behaves differently
when mounting on a different environment.
So we test the antenna in four
different settings
a) free space
b) on top of a 150 x 90mm ground plane.
(A common ground plane size for
electronic device)
c) on the edge of a 150 x 90mm
ground plane.
(Another common way of
mounting antenna)
d) 450 x 350 ground plane.
This simulates the situation of mounting
TG.09 on top of a large metal object,
such as a vehicle.
TG.09 can be installed in 5 different
angles so we present the test in
different combination of angles
and mounting environment.

TG.09 on top of a 150 x 90mm PCB.
?SPAN class="pst TG-09-0113_2601012_0"> is the horizontal rotation and 0 is the
vertical position of TG.09 with respect to
the 3D chamber.
In the Satimo chamber, ?/SPAN> = 0 is the
x-axial, ?/SPAN> = 90?is the y-axial and
0 =180?/SPAN> is the z-axial.
