hello evryone for circular polarization axial ratip should be less than 3 dB right?but my axial ratio is not like this also i want to ask one more thing do i consider axial ratio at both port or only single one?
Why are there two different results?
Are you exciting the two ports separately?
Onthe other hand, the scale of the vertical axis is not clear for me. Can you clarify?
And please show the plot of directivity.
yes there is two ports ..and m exciting these separately...what to do please tell me
vertical scale is showing axial ratio..
and here are the plots of directivity.
You should study some basics about antennas.
When asking for help, you should give clear information. For example, it remains unclear how is the design.
