Very nice antenna Admin. Could you give the reference paper to this radiator ?
-
@sandeepv thanks, could you give me the title of this paper ?
-
Ok thank you
-
Do you have a reference for this antenna ?
-
Yeh, your project gave S11 = -14.09 dB but it's value -42.37 dB in your first post.
-
result of simulation of your project :
-
Did u measured the S11 parameter and the radiation diagram ?

I'm using CST MWS 2017. 've opened your project and now i see my problem. I've used PEC sheets and the dimensions are not the same. This is why we got different results. Now for circular polarization, usually we demand to plot axial ratio versus frequency in cartisian system AR = f (frequency) to prove that the antenna is circularly polarized. I think that there are some changes in the far field propreties. What do u think ?
-
Do you have a reference to this antenna ? Also, may be the meshing is not good.
-
This is what i've obtained :
-
So what dielectric did you used for the antenna ?
-
Oh no, excuse me Admin i have made a mistake. In fact, i've created this material and renamed it to foam.
-
Hi, I worked with foam loaded from CST material library. The relative permittivity of the dielectric is 2.2.
-
In fact i want to knowhow to plot Axial Ratio of a circularly polarized antenna Vs frequency (tha gragh is a cartesian one AR =f(frequency) ). I tried your model but i can't get the same results. I've attached the project. So could you tell me please what was wrong with the model and how to deal with the AR. U-Slot Patch Antenna.cst

For circularly polarization, can you offer axial ratio vs frequency and the method to obtain this result.

Very interesting, thank you
