estqwerty’s wifi antennas

18 or 19dBi - no mater for this one . Several dipoles printed on PCB board. Have more dipoles You get more dBis. Will it be 10 12 or 24 - You decide how much do You need.

This is defiantly homemade design. I have one small antenna whit only 4 dipoles - and it works great, so this antenna should work fine. Also will be easy to be rescaled for other bands - 2.4Ghz or 5Ghz only change dimension of the dipoles.

19dbi panel wifi antenna link to picture

Here is the photo from the other side of the pcb board and other part of feeding element

Picture is from this address : diy.wifi-live.pl/node/4 where also have blueprints for less dbi antenna .

On www.zero13wireless.net also has several files posted by sushisan .

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.

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.

Very Cheap Dipole feeders - they are easy to be build and you do not need a lot or expensive materials. Everything here can be made from wire or scrap /I watch too much scarpwars on Discovery channel /

I found some very interesting looking feeders for dishes - VERY cheap to make, first is made only from feeder line or simple coax.

“A simple dipole feed. Good solution to illuminate parabolic constructions (solid, grid etc.) Heliax holds the dipole, as well as feeds the N-type female connector to the back. Tests shown 4 dBi (against Lucent 24 dBi parabolic grid). “

Second is Russian of course http://www.hub.ru/forum/index.php?showtopic=16285

Name of the file is interesting too D_Linc3_008.jpg

Interesting materials - onli several pieces of pcb board are used - very good.

From the same forum are these too -

Last pic is from http://martybugs.net/wireless/conifermods2.cgi

And for the end howto make wire reflector or DIY Parabolic Grid Reflector

19dbi gird blueprint :

For me is easy to buy small offset dish - 80cm is around 10 to 15 Euros here.

D-Link Ant24-1200 Sector Panel Antenna

Gain : 12 dbi

web site : www.zero13wireless.net

So I make one but still cant get it working.

In the test witch netstumbler - i get too low results - may be something is wrong, maybe material of pcb board is not the same

My TEST for dwl 12dbi thing something is wrong whit my ones :

this is room test - distance ~2m
linksys wap11 whit original antenna - AP
zydas zd1211 usb whit rpsma connector soldered and 5 cm coax soldered to antennas.
various antennas tested to be able to compare result.

Second test - tv tower ~1.5 to 1.8km

Same antennas - near same ressults
rubber duckie 2dbi , smc 11 clone , trend omni - original , interline 14 dbi clone and dwl 12dbi

I tried different position of the reflector I used another piece of pcb - no results .
Maybe the material of the pcb board does matter???

Another thing is the low result of interline 14 panel - i was tested it before and get good results.

I’ll make some more tests but i’m loosing faith in this one

Here is the link to the forum from where i take blueprints for this one http://wireless.com.pt/forum/viewtopic.php?t=14978
