trying to make a broadband patch antenna 5.6 to 5.9 Ghz, probably on 62 mil thick FR4 board. I am close, but just can not get the final dimensions to give good VSWR across the whole band. Only getting maybe 6 dB return loss over the band on an E-shaped patch. It is really touchy, and each analysis pass takes a while...I may never converge on the final correct dimensions. (yes, I know it would be easier on a thicker substrate, or lower dielectric constant--like air, but I need it to be "cheap" and very manufacturable for a commercial job)
Anybody have dimensons on such a beast?
