Tin foil FM antenna tuner

Please help me to design small calculated FM antenna made from tin foil, with tuning capacitor also made from tin foil? It's a bit confusing trying to apply the mag loop calculators for the short wave. It should be rather small and wide, than big and thin. So it's possible to use many of them in parallel on small space.
 

What kind of antenna? Beverage?

Rather like wide flat magnetic loop, that can be glued on both sides of A4 or A3 paper. So it's more about the surface tension, not about the length. Intended use would be cheap energy harvesting, for those regions who are not using AM frequency anymore.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
