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"??

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...
