how can i plot patternAzimuth in app designer?

I have the following code :

antennatx = phased.CustomAntennaElement('AzimuthAngles',az, ...

'ElevationAngles',el,'MagnitudePattern',magpatterntx, ...

'PhasePattern',phasepatterntx); % It models the trasmitting antenna element with a custom spatial response pattern

patternAzimuth(antennatx,fc,'PropagationSpeed',c)

I have to plot this grafic in app Designer, how can i do this?

Hi Palma Errico,

It is my understanding that you want to plot the “patternAzimuth” in the App Designer. To achieve this, you can use the “plot” function. Here is a sample code for the same:

% Button pushed function: Button
function ButtonPushed(app, event)
    fc = 2.4e9;  % Example carrier frequency of 2.4 GHz
    c = 3e8; 
    az = linspace(-180, 180, 361);

    % Define the elevation angles for the pattern
    el = linspace(-90, 90, 181);

    % Define the magnitude pattern for the transmitting antenna
    magpatterntx =  ones(181, 361);

    % Define the phase pattern for the transmitting antenna
    phasepatterntx =  ones(181, 361);

    % Create the custom antenna element
    antennatx = phased.CustomAntennaElement('AzimuthAngles', az, ...
        'ElevationAngles', el, 'MagnitudePattern', magpatterntx, ...
        'PhasePattern', phasepatterntx);

    % Plot the azimuth pattern in the UIAxes
    plot(app.UIAxes, az, patternAzimuth(antennatx, fc, 'PropagationSpeed', c));

    % Set the x-axis label
    xlabel(app.UIAxes, 'Azimuth Angle');

    % Set the y-axis label
    ylabel(app.UIAxes, 'Pattern');

    % Set the title
    title(app.UIAxes, 'Azimuth Pattern');
end

You can refer to the following documentation to know more about the functions used:
