wlan splitters more …

I was thinking about this one :

“… The doubling of the output power is equivalent to a 3 dB increase in the signal. If the combiner is 90% efficient then a 2.5 dB gain is seen. Note the dichotomy:

· If the antennas point in different directions, there is a 3.5 dB loss at the combiner.

· If the antennas point in the same direction, there is a 2.5 dB gain at the combiner.

(This is a 6 dB swing. 3 dB of this is just the adding of the second antenna, but the other 3 dB is from the combiner becoming a much more effective device.) … ”

If someone understand this and have any info Please send me a link, or tell me what to look for.

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 !!!

spliter-napoly.jpg powersplitter Similar to up picture but using coaxial cable.

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 :
