D-Link ANT24-1800 18dbi wlan antenna

Wednesday, July 25th, 2007

Some NEW info is available about this antenna new pictures here.

This one look interesting so here some info about it.

Most of the info came from these sites :

So no doubt that russians show this antenna to the world – Thanks !

More antenna specifications

Input : 50 ом

Frequency range : 2.4 -2.5Ghz

Gain : 18 dBi

Polarization : Linear, vertical

VSWR 1,5 max

Diagram : horizontal – 15° vertical- 15°Dimensions : 360 x 360 x 16mm

More pics can be found in the upper sites.

Drawings from elk again d-link 1800.rar but on You can find another two files which may be the same – I’m not shure.

Dimension between pcb plate and reflector is 9mm.

I’m not sure but, this antenna will be hard to reproduce because we do not have info about thickness of substrate nor dielectric constant of the material. So this is not a option to build and test for me right now.

Wlan Antenna Splitters

Wednesday, July 4th, 2007

At last I have collected a lot of pictures of different wlan antenna splitters .

Some blueprints and links too.

Some dimentions ARE NOT for 2.4ghz !!!

Wilkinson power splitters.


This is just a pics found in the net or cant remember links for them.




The idea/may be/ and ps file and this pic 800 mhz splitter are from here

If some one explain me this thing here I’ll buy a couple of bees 😉
“It is possible to use old 800 MHz cellular phone power dividers/combiners at 2.4 GHz because of the 3rd harmonic relationship.

Different designs :


spliter-n.gif I found this one completed whit some pics – sorry again can’t find link to original file. Send me a link if You know it.

Next there is another 4 way coax splitter :

You can search for 23cmhybrid.pdf or Hybrid-Double-Quad-Array-D.pdf

Last this one is without coax :
