Hi, i'm unable to achieve right hand circular polarization for all the bands in my tri-band patch antenna. none of the conventional methods like side truncation or adding slots seems to work. can someone suggest an alternate method to obtain rhcp for all the bands in a tri band patch antenna. thanks in advance.
 

Do provide some more details ?
The questions that arise are -
1) What bands/ applications are you designing for ? GPS/ CNSS ??
2) What actual topologies have you used ?
3) How do you know it is "not working" ? What test setup etc etc have you used. Which bands worked and which did not ?

etc etc
 

Hi, I'm designing a patch antenna for GPS application in HFSS software. all the dimensions of the patch are as per calculations. I have three frequencies resonating at the required frequencies. However, the axial ratio vs frequency plot does not satisfy the RHCP condition (<3dB). I was able to achieve a -3dB axial ratio for the lower band but not for higher frequencies.
