Hello All!

I need patch with good axial ratio. It shold be symmetricaly excited (like simmetric vibtator). Can you help me?

Thanking you in anticipation!

PS hmm, why word "p@atch" is replaced by "fix"??

Can u give some more information? Is the axial ratio the main request? How about form, substrate freq and son on? Are those optional?

Best Regards

AR should be in range 0.4-1, substrate with epsilon~2-6 with no ground plane, resonance between 800-1200MHz. Antenna should be planar and feed shoul be in the same plane that patch.
I try simulate some kind of slot antennas, but without success...
