before the modification of design, did you choose a good dimension for your radiation box? LAMDA/4 minimum. also boundaries conditions are very importants...
where is your excitation port?
it's not necesary to change εr if you need to get rid lobes. Good directivity is based on optimal coupling between the dimensions of the 5 composants of your antenna. I proposed you to optimize dimensions paramaters using "transient solver-par.sweep"
passive circuit in height frequency
hi
i need a simple analytics expression of height frequency passive circuit. to find capacitance and inductance for example base on metallics lines and relative permittivity of substrat
hi ferdow
it's really difficult to export complex S parameters from CST, i used finally HFSS because you have possibility to enter equation and obstain all paramaters you need! it's very simple with HFSS
I have a first problem!
The expressions of permittivity and permeability are given by complex S parameters (i think)!!!
But CST gives S magnetude (linear) and S(dB)!
What's the S paramters that you exported?
i will absolutly send you result... thank you for all
"sorry for my english! i speak...
thank you ferdow

this tutorial is very interesting, but it don't presents permittivity and permeability just the S parameters.
hi
i want to plot a function of frequency of the permittivity, permeabilitty and refraction index "n" of an unit cell with CST microwaves 2010 (see figure below).
i can just represente S11 and S21, impedance Z.
can anyone help me please!
hi,
I have a problem of representation of polar curve with CST.
Indeed, I can save a 1D curve cst in text file (eg S11, "file-export-plot data"), to import the same file in CST, I am: "macro-file-import-1D signals"
how to do the same with a curve in 2 dimensions? such a radiation pattern in...
hi,
i'm designing an horn planar antenna with HFSS! but i can't use my solution setup (16Ghz) because simulator said: "an extremely large mesh will be required to produce an accurate solution" (see the document loaded).
with antenna dimensions (24*60*12)mm, i can use 16 Ghz solution setup BUT...
exitation
hi,
I'm working with CST simulator, but i don't know how excite the port of this antenna!! i use the S discret port parameter! where can i put the port?
help please!
simulation rfid antenna
hi,
I'm working with CST simulator, but i don't know how excite the port of this antenna!! it's the S discret port parameter! where can i put the port?
help please!
