    Syntax

    arr = createArray(obj,freq)
    [___] = createArray(___,Type="phased")

    Description

    arr = createArray(obj,freq) creates a conformalArray object based on the input parameters specified in the phased array calculator. Generated antenna array acts as an initial set up which you need to optimize and tune by varying the inter-element spacing for a better performance.

    example

    [___] = createArray(___,Type="phased") creates a phased.ConformalArray System object™ based on the input parameters specified in the phased array calculator. Generated phased array acts as an initial set up which you need to optimize and tune by varying the inter-element spacing for a better performance. To use this syntax, you need a Phased Array System Toolbox™ license.

    Create a hexagonal phased array of conical horn antennas. Set the expected array gain to 27.5 dBi, element efficiency to 55%, and scan angle to 12°.

    p = phasedArrayCalculator(Lattice="hexagon",...
    RadiatingElement="conicalhorn",...

    Create and visualize a conformalArray object operating at 1.57 GHz from the phased array calculator.

    arr0 = createArray(p,1.57e9)
    Calculated Spacing is increased to avoid intersection between elements.
Approximate memory needed to solve the structure:170 GB. For large memory requirements use patternMultiply (or) phased.ConformalArray.

    arr0 = 
  conformalArray with properties:

            Element: [1×1 hornConical]
    ElementPosition: [37×3 double]
