How to tune my POTY Patch Antenna

Why do you want to do that? The idea is the wanted band is between the two resonances to get good circular polarisation. The response looks fine to me. The highest resonance is at the cut off corners so bending slightly towards the ground plane might work or perhaps a bit of kapton tape.

Hello Daniel,
I am looking for an Spectrum Analyzer. Which do you use ?
Thanks

Hi Uli
Just google for 'Simple Spectrum Analyser D6 with Trace Generator'. Its about 50 USD and results so far on other antennas were satisfying. I recommend to use the 'SNA Sharp' software from F4HTQ (simple to use as a starting point).
