wireless 2.4GHz 14.2 dBi horizontal polarized directional panel antenna

Wireless patch panel 2.4GHz 14.2 dBi antenna
This is a very interesting design, small form, but has 14dBi gain, it is excellent for use in a range of 3km. make it easy just need the PCB double layer and aluminum as the reflector. in the images can see the size of each side of PCB.
