archimedean spiral antenna with cst

hi all,
can anyone help me with designing archimedean antenna with cst.
esp. the excitation.. how to use the lumped element port.. which material that i should choose.. etc
and if u dont mind, please upload one of your design for example..
thank you for your help

regard.

Hi
The best way for designing spiral antenna is using of matlab program and then importing at cst
i will send you a code soon

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

i also need matlab code to design Archimedean spiral antenna design?
can you send it to me this email id: (kallyany@gmail.com).

can you tell me how we can import to CST from matlab?

thank you

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 maximal10,

I am working with this type of spirals. Can you send me the mathlab code, please?

Thank you

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

can i too have the code?

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

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)
