Importing data from HFSS and ploting in matlab
显示 更早的评论
I designed a dipole in HFSS and exported the polar radiation pattern in csv format to matlab. now, i need help on how to plot the data and get the same result as HFSS. I also attached the raw csv format.

Good Evening Mordecai. The following code ingests and plots the data in a figure for each Phi angle. Please let me know if you have any questions.
[num, txt] = xlsread('pat.csv');
theta_polar_deg = num(:,1);
theta_polar_rad = deg2rad(theta_polar_deg);
for i = 1:length(txt-1)
figure('Name',txt{i},'NumberTitle','off','MenuBar','none');
Gain = num(:,i);
polarplot(theta_polar_rad, Gain,'r')
rlim([min(Gain)-5 max(Gain)+5]);
ax = gca;
ax.RTick = [-38 -26 -14 -2];
ax.ThetaDir = 'clockwise';
ax.ThetaZeroLocation = 'top';
plotTitle = sprintf('Radiation Pattern %d',i);
title(plotTitle)
end

Good evening. I accidentally added the -1 inside the parenthesis, it should have been for i = 1:length(txt)-1. Please try the updated code below:
[num, txt] = xlsread('pat.csv');
theta_polar_deg = num(:,1);
theta_polar_rad = deg2rad(theta_polar_deg);
for i = 1:length(txt)-1
figure('Name',txt{i},'NumberTitle','off','MenuBar','none');
Gain = num(:,i);
polarplot(theta_polar_rad, Gain,'r')
rlim([min(Gain)-5 max(Gain)+5]);
ax = gca;
ax.RTick = [-38 -26 -14 -2];
ax.ThetaDir = 'clockwise';
ax.ThetaZeroLocation = 'top';
plotTitle = sprintf('Radiation Pattern %d',i);
title(plotTitle)
end

Hello Mordecai. I'm not sure why you got that result. I noticed in the CSV, column A has the theta values, so I modified the code to omit this column in the loop (that's why it is now "for i=2:length(txt)"). Please try the below code, I've attached an example of the output I am getting. Let me know if this works!
[num, txt] = xlsread('pat.csv');
theta_polar_deg = num(:,1);
theta_polar_rad = deg2rad(theta_polar_deg);
for i = 2:length(txt)
figure('Name',txt{i},'NumberTitle','off','MenuBar','none');
Gain = num(:,i);
polarplot(theta_polar_rad, Gain,'r')
rlim([min(Gain)-5 max(Gain)+5]);
ax = gca;
ax.RTick = [-38 -26 -14 -2];
ax.ThetaDir = 'clockwise';
ax.ThetaZeroLocation = 'top';
plotTitle = sprintf('Radiation Pattern %d',i-1);
title(plotTitle)
end

P.S. This is the pat.csv file I was using, if it doesn't match the format you are using that may explain why you got a different result.

I have same project so i do your work but i give this error. What can i do?
Error is: Undefined function 'polarplot' for input arguments of type 'double'.
Error in Help (line 10) polarplot(theta_polar_rad, Gain,'r')

Hi Mahdi, I think it's your MATLAB version. Instead use the function 'polar' instead of polarplot. I.e polar(theta_polar_rad, Gain, 'r')

thank you. I use new version of MATLAB and it work.
