How to combine two diffrent antenna figures into one

Hey everybody, i am finished with my knowledge and need your help now. As i already wrote into the titel, i need help with combineing two diffrent antenna figures into one. Therefore i have made two yagiUda-Antennas with the same configurations but they shall be rotatetd 90° about the other one (so the one is like an x and the other one ist like an +). But unfortunately i dont get it. I tried a lot and can tell you that plotting doenst work because they arent made out of plots. Otherwise if there is no opprtunity to combine them i would be interested into how i can create an crossed Yagi-Uda-Antenna in Matlab. Thank you for your help.

Best Regards.

@Marvin Hope this is what you want:

% Check for Antenna Toolbox availability
if ~license('test', 'Antenna_Toolbox')
    error('Antenna Toolbox is not available. Please install it to run this example.');
end

% Define the operating frequency
freq = 300e6; % 300 MHz

% Create the first Yagi-Uda antenna
yagi1 = design(yagiUda, freq);

% To rotate the second Yagi-Uda antenna, we first create it
yagi2 = design(yagiUda, freq);
% Apply rotation
yagi2.Tilt = 90;
yagi2.TiltAxis = [0, 0, 1]; % Rotate around the Z-axis

% Visualize the first Yagi-Uda antenna
figure;
show(yagi1);
title('Yagi-Uda Antenna 1');

% Visualize the second Yagi-Uda antenna (rotated)
figure;
show(yagi2);
title('Yagi-Uda Antenna 2 (Rotated)');

% For analysis or simulation, create a conformalArray with both antennas
% Note: The positions and orientations must be carefully set for accurate modeling
conformalArray = conformalArray('Element', {yagi1, yagi2}, 'ElementPosition', [0 0 0; 0 0 0], 'Tilt', [0, 90], 'TiltAxis', repmat([0 0 1], 2, 1));

% Visualize the conformal array
figure;
show(conformalArray);
title('Conformal Array of Combined Yagi-Uda Antennas');

Hey, to give you a Feedback. I just can say that it safed my day/week and i am very thankful for this response. Therefore i have one or maybe later a couple of questions if its ok :)

For example would i like to know if i can add there a boom in the middel or do i need to use the "quadCustom" function ? And i woud like to know which parameter do i need to change when i want to rotate the Combined YagiUda Antenna so that the length of the boom/spaceing of the diffrent elements is into the y-Direction ?

I also would like to know if i can start optimizing this combined antenna now and if i can analyize some data out of that like the readdiation pattern, ez/al angle, impedance and more ?

Best Reagrds! And again thank you!

% Check for Antenna Toolbox availability
if ~license('test', 'Antenna_Toolbox')
    error('Antenna Toolbox is not available. Please install it to run this example.');
end

% Define the operating frequency
frequency = 300e6; % 300 MHz

% Design the first Yagi-Uda antenna for the specified frequency
yagi1 = design(yagiUda, frequency);

% Create a copy of the first Yagi-Uda antenna for the second antenna
yagi2 = copy(yagi1);

% Rotate the second Yagi-Uda antenna by 90 degrees around the z-axis to achieve
% the crossed configuration
yagi2.Tilt = 90;
yagi2.TiltAxis = [0, 0, 1];

% Create a conformal array to combine both antennas
crossedYagiArray = conformalArray;
crossedYagiArray.Element = {yagi1, yagi2};
% Assuming both antennas are placed at the origin, but you can adjust their positions if needed
crossedYagiArray.ElementPosition = [0 0 0; 0 0 0];

% Visualize the crossed Yagi-Uda antennas setup
figure;
show(crossedYagiArray);
title('Crossed Yagi-Uda Antennas');

% Note: This script creates two identical Yagi-Uda antennas, rotates one by 90 degrees to
% achieve a crossed configuration, and then combines them in a conformal array for visualization.
% Further analysis can be performed on the 'crossedYagiArray' object using Antenna Toolbox functions.
