Hi maiximal10,

can the MATLAB code generate a Archimedean Spiral shape with specified measurements and dimension without importing them to CST?

Would u mind to share the code with me too? Many thanks...

Hi maximal10.
Please, I work on my thesis and I need the Matlab code too. Code for Archimedean spiral antenna. Could you send it to my email adress?? ( radulus(at)seznam.cz ) I need to design spiral antenna for frequency range 100MHz - cca 10GHz. I have to make it in Matlab, or CST Microwave Studio. Please help me too.
I realy thank you. Have a nice day

Would you also please send me the code?

This is my e-mail: ozcanhu[at]gmail.com

I design a spiral antenna between 800 MHz - 6 GHz, circularly polarized, using CST MWS.

Thank you very much in advance!

hi
how do you import the matlab code into cst? or how do you generate the spiral? I have the code but I don't know the next step:( in CST
thanks

howdy dudes,

As for the matlab code to generate a spiral, you may kindly try this piece of code out.


% Parameter:
r = 2;
dz = 1;
t = 0:0.02:5;
% Spiral computing:
x = r*sin(t*2*pi);
y = r*cos(t*2*pi);
z = dz*t;
% Spiral computing:
hold off;
plot3(x, y, z, 'linewidth', 1.5);
% cylinder computing:
[cx,cy,cz] = cylinder(2);
cz = t(end)*cz;
% draw a cylinder:
hold on;
surf(cx, cy, cz, 'facecolor',[0.5 0.5 0.5], 'facealpha',0.5);

Reckon that CST imports files of format (.m), I'm myself damn new with it.

Best regards

Rodeoman:grin:

Hey! Is'n it easier to create a spiral directly in CST, using an "Analitycal curve"?

[/url]

Here N is the number of turns, a is the maximum radius, and b - height coeff. of the spiral. (Full height is h = b*pi*N)
