1, Download Template Below
2, Open in MS Paint and resize as desired. Ensure that you keep the square on the diagram square.
3, Print image on business card stock or acetate (document protector) or glue to cardboard !
4, Cut it out and open the six slots with sissors or an X-Acto knife.
5, Glue tin foil to the back side of the reflector surface
6, Assemble by placing the six tabs in the six slots.

Note: If printed at the download size you will see about 9 dBi of gain. If you double the size of the image before you print it you will see about 12 dBi of gain. If you place two reflectors on an AP with two antennas you will see an additional increase in performance.

There's also WokFi

WokFi (a portmanteau derived from blending Wok + Wi-Fi) is a term now commonly used to indicate a style of Wi-Fi antenna made out of simple low-cost Asian cookware scoops, or similar easy to find household metallic reflective items.

...

WokFi antennas can be fabricated out of commonly available scoop-shaped utensils (which need not be perfectly parabolic) in conjunction with a USB Wi-Fi dongle. This approach is considered simpler and cheaper than classical home-built antenna projects (such as the popular Cantenna), but is a very effective method to boost the Wi-Fi connection quality, audit access point coverage, and even quickly establish WLAN viability -- perhaps if a more professional setup is eventually intended.

And Cantennas

A cantenna is a directional waveguide antenna for long-range Wi-Fi used to increase the range of (or snoop on) a wireless network.

Nice.
I build a couple of the uhf dtv antennas featured here in another thread, and the work great here on the fringes.
Maybe I'll try making one of these out of a foil baking sheet.

these antenna's work pretty good for what they are , , simple simple !
ive changed the logo on those an give em out somtimes for folks , kinda like a biz card , lol

though like lysergic pointed out there are many ways an antenna types that you can use ..

i preffer yagi antenna's but they take more work and material , here is a badass one i use alot :
