Wow.

I'm too close to Kennedy Space Center to dream of 7w.
I can see it on the news, "Delta Rocket veered Off course, had to be destroyed"

LOL

Hi guys.
This weekend I "separate" some time for me so I make 3 biquads, all for 2,4GHz band.

Stacked biquad is made according to picture

Description:

I use 1,8mm wire for all three antennas.Reflector for stacked biquad is little smaller 170x200 than needed (200x200).
Tested by WiFi router and NetStumbler.BiQuad and BiCircle have same gain (doesn't have pic from stumbler). Also I didn't made measurement of directivity, just direct to PC (through the wall).

Omni (stock), Microstrip 11dBi (from Flytron) and stacked biquad.
BiQuad is currently under roof as WiFi antenna so it is not included in this test.

I found the stacked biQuad dimensions to be a little bit off. You also need to make the reflector plate much larger to accomodate the parasitic element. For the stacked BiQuad, the reflector should be 1.5 wavelengths instead of just 1 wavelength as in this tutorial.
