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

Click to expand...
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...
