Re: The "Cantenna" has not 12 dBi!!!

Nope. The traces between the feed point and the beginning of the
dipole elements might be 50 ohms (they're not, but close enough).
However, the other elements a fairly high impedance and should be
quite a bit thinner than shown.
how can i find the impedance for the microstrip width?

Duz it have anything to do with the original question?
sorry, this has nothing to do with the original topic of cantenna..

i which to build that omni PCB, but i only recently started at RF..so i
dont have enough knowledge to make the antenna.

Here's another large 2.4GHz horn antenna used in the 2003 WiFi long
distance (DX) contest:

(Near bottom of page). Made with a metal tubing frame and covered
with aluminium window screen wire mesh.
that´s a very big horn, how much dBi that antenna will have?

the world record wireless distance is 237.36miles, 'link'
