patternSystem
Visualize radiation patterns of multiple antennas installed on platform
Since R2024a
Description
patternSystem(___,Name=Value)
plots the radiation
patterns with additional options specified by one or more Name-Value Arguments.
Examples
Radiation Patterns of Antennas Installed on Glider
Create a platform from the STL file containing the geometry information of a glider. View the platform.
plat = platform(FileName="glider.stl", Units="m"); figure show(plat);
Design a regular and a circular microstrip patch antenna operating at 2GHz. Install these antennas on the glider wings. View the glider with installed antennas.
elem1 = design(patchMicrostrip, 2e9);
elem2 = design(patchMicrostripCircular, 2e9);
ant = installedAntenna(Platform=plat, Element={elem1, elem2},...
ElementPosition=[-3.15 1.1 0.12; -3.15 -1.1 0.12]);
figure
show(ant)
Visualize the radiation patterns of the installed patch antennas.
figure patternSystem(ant, 2e9, ElementNumber=1:2)
Input Arguments
object
— Platform-installed antennas
installedAntenna
object (default)
Platform-installed antennas to plot radiation patterns, specified as an
installedAntenna
object.
Example: installedAntenna(Element={discone,monocone}, ElementPosition=[0.1
0.1 0.5; -0.1 -0.1 0.5])
frequency
— Frequency in Hz to plot radiation pattern
positive real scalar | positive real vector
Frequency in Hz to plot radiation pattern, specified as a positive real scalar or
vector. When you specify the frequency as a vector, the number of elements must match
the number of antenna elements in the installedAntenna
.
Example: 70e6
Example: [70e6 80e6]
Data Types: double
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Example: ElementNumber=1:4;
ElementNumber
— Index numbers of antenna elements to plot radiation patterns
positive integer scalar | positive integer vector
Index numbers of antenna elements to plot radiation patterns, specified as an integer scalar or a vector.
Example: 1
Example: [1 2 3 4]
Data Types: int16
| int32
| int64
PatternOptions
— Plot visualization options
PatternPlotOptions
object (default) | vector of PatternPlotOptions
object
Plot visualization options, specified as a PatternPlotOptions
object. Specify PatternOptions
as a vector of PatternPlotOptions
object to set the
PatternOptions
of individual antenna elements.
Example: PatternPlotOptions(Transparency=0.6, MagnitudeScale=[1
10])
Example: [PatternPlotOptions(Transparency=0.6, MagnitudeScale=[1 10])
PatternPlotOptions(Transparency=0.3)]
