meandering technique for microstrip antenna on 2.4 GHz

Dear all,
Harys my name, and I am a beginner to make antenna
I made ​​an antenna for my job in my college years.
And there's something I want to ask you.

I have designed on microstrip patch antenna panel with meandering methods and working in 2.4 with the help of Ansoft HFSS ..
but I am here have difficulties in determining my HFSS antenna with a good grade because I was in the HFSS simulation was 37.7428 dB. and here I am still confused how to get circular polarization on the design of my antenna and the antenna gain mendapatakan good value ..

Maybe someone wants to help fix my antenna design is to obtain parameter values ​​antenna VSWR, gain antenna, Polaradiasi antenna, circular polarization antenna is good. I will attach my antenna design results in a gain value of 37.7428 dB VSWR.

I Hope you want to spend your time helping me
Thank you for your attention
I'll wait for you ...

Thank you
