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

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
<

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°.
