I remember that integration IA4420/21 had documentation and layouts (in



pdf) of various pcb antenas for 315/433/868/ 915MHz,  i couldn't found



the original url now. The files are IA_ISM-AN1.pdf and IA_ISM-AN2.pdf



you can still found them, if not ask me by email. I start a design but



bought it already made and cheaper...
