Another Yagi whit interesting design, this time from Dlink.

Original link : http://www.zero13wireless.net/foro/showthread.php?t=1150

PDF Specification : http://www.dlink-me.com/ftp/antennas/pdf/ANT24-1201.pdf

Gain should be around 12dbi.

And here it is what is inside : usual yagi directors are madded from aluminum /i think/ and pcb dipole used as feeding element.

You are wondering were did You saw similar dipole feeding ??? I tell You : http://www.digdice.com/2007/09/28/sector-antenna-grad2487/
The feeding of the dipole is very similar.

Dimensions for this antenna :

Omni-directional microstrip antenna

there is two microstrip antennas :

Design of this one is based on this pdf file : wp_omni_wireless.pdf You may search in internet for it.

I was tested this BUT without proper material for the pcb - nothing is going on. I’ll search for some old photos.

And second one :

This one is used in older netgear and proxim devices.

Recently found this one selling - this is good sign usually. Good that i have some more pics of this antenna. Blueprints are lost between my drives.

Keys to search in google - MA-WA58-1X and A73102

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
