I don’t like Yagi antennas /sorry/, and I never try to make one , but this look interesting – it is only one side pcb design that differ from the most dual sided similar.
On the side is said that this antenna is a clone to a commercial one, but not a name or model is mentioned.
The dual sided board is needed to make the feeding point of the yagi antenna – here we have something very interesting and different to be able to make all needed parts on one sided PCB board. In fact this is dipole.
Link to the page : http://www.aribg.it/Tech/WiFi/Yagy24ydm/yagi24ghz.htm
Here is schematic :
Here some pictures whit dimensions :
On the second picture You can see haw to assemble the dipole – this is the interesting part. This antenna is feeded by dipole not whit loop like most Yagi antennas. Here they make a balun whit the stripped coax and the pcb board.
There is also one aluminum disk used to hold the board that is used as reflector :
On the site is said that this antenna have 11.5dB gain. And for last there is a SWR test for this antenna pretty good results I thing :
The peek is little out of wifi band but we still may get very good results for wlan applications.

1/8″ brass rod$3.49, 1/2″ CPVC plastic plumbing pipe $?had a leftover scrap,
The driver loop I made out of the same brass as used in the elements instead of the flat 4mm specified.
Use RG58U cable wired directly to antenna driver element, use short as possible as there is about 1/2 dbi loss per foot of cable used.
The antenna has a 15 dbi gain.
I soldered a 54mb usb adapter to a 1″ length of RG58U and mounted the board behind the reflector element. conect to computer with a 15′ usb cord and there is no loss signal.
excus me..
@how many distance betwen driven part and 1st dirrector..?
@how many distance betwen 2 wings driven?
thank you very much..

hi ? what other mistakes? please be more concrete?

There are other faults
It works perfect! Just open the layout picture with motzila, choose print preview and scale with 63% zoom. Print it. Thank you.
