    Syntax

    plot(obj)
    plot(___,Name=Value)

    Description

    plot(obj) plots the phased array layout at 10 GHz. To use a different frequency for the plot, specify the Frequency name-value argument.

    example

    plot(___,Name=Value) plots the parameter specified using one or more name-value arguments.

    Create a square phased array of rectangular patch antennas and set the expected array gain to 25 dBi. Choose the array operating frequency at 1.75 GHz.

    p = phasedArrayCalculator(RadiatingElement="rectanglepatch", ArrayGain=25)
    p = 
  phasedArrayCalculator with properties:

                 Lattice: 'square'
        RadiatingElement: 'rectanglepatch'
               ArrayGain: 25
       ElementEfficiency: 100
       IlluminationTaper: 0
               ScanAngle: 6
               TaperLoss: 0
             AntennaLoss: 0
       PointingErrorLoss: 0
        BeamDiameterLoss: 0
    ImplementationMargin: 0

    Visualize the array layout at 1.75 GHz.

    Figure contains an axes object. The axes object with title Grating Lobe Vs Spacing (@ 1.750000e+00 GHz), xlabel Element Spacing (m), ylabel Angular Location of Grating Lobe(°) contains 4 objects of type line. These objects represent Grating Lobe Location: Boresight, Grating Lobe Location: 6° Scan.

    Analyze array efficiency with reference to radiation strength across array elements.

    Figure contains an axes object. The axes object with title Efficiency vs Illumination Taper (@ 1.750000e+00 GHz), xlabel Illumination Taper (dB), ylabel Efficiency (%) contains an object of type line.

    Input Arguments

    collapse all

    Phased array performance parameters, specified as a phasedArrayCalculator object.

    Name-Value Arguments

    collapse all

    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: Type="gratinglobe"

    Array operating frequency, specified as a positive scalar. The default operating frequency is 10 GHz.

    Example: 15e9

    Data Types: double

    Type of parameter to plot, specified as one of the following strings:

    • "layout" — To plot array layout

    • "gratinglobe" — To plot grating lobes as a function of inter-element spacing

    • "efficiency" — To plot efficiency as a function of illumination taper

    Example: "efficiency"

    Data Types: string
