need of Dual Band antennas

[zach.antre 0]

Hello guys,

 

I am a wireless networks enthousiast and I really like mesh networks. I found this website by searching on how to build my own antennas (though I do not have radiowave knowledge, I am pretty good at building staff). This is my 1st post on this amazing forum and I have red almost all posts but I am not really sure if I have found what I need (too many information), so I am writting this post in order to get some help from people that have better knowledge than me.

 

I own several Meraki MR16 APs flashed with OpenWRT firmware and I would like to create a mesh network and provide free wifi to the people living in my village. The concept is to combine 2 MR16 on each place, 1 for mesh networking (backhaul) and 1 as AP.  There are several houses over 1km away and for that I would like to use high gain omni and directional antennas

The MR16 has 2 small dual band omni antennas

Ideally what I need is 2 MIMO Dual Band (2x2:2) antennas  (1 omni and 1 directional) but at least for omni I don't even know if it is possible.

for sure I need the antennas to be dualband and able to controll polarisation in order to avoid interference

So, any suggestions please?

btw, I have found some designs in a proposed website by Admin

"Well, but your access point has two antennas, one with vertical polarization and one with horizontal polarization...

 

Here is a side view of the 2.4GHz antenna.

Here’s the top down view of the 5GHz antenna on the MR-16 AP.

 

Both are F-inverted antenna...!!!

 

And what kind of antenna do you want ... and for what frequency?

Actually both radios use the same antenna for each stream.

I have tested them by unplugging them one by one.

The frequencies I need are for wifi 2.4GHz and 5.5-5.7GHz (for outdoor)

I need 1 dualband omni horizontal polarized

1 dualband omni vertical polarized

1 dualband directional horizontal polarized

1 dualband directional vertical polarized

,,, aaaa, okay, so it has separate antenna ports for both 2.4GHz and 5.5GHz respectively...!!!!

well, from what I have tested this is how is made:

1 dual band vertical polarized antenna

and 1 dual band horizontal polarized antenna

 

it has seperate antenna for 2 streams (150mbps each stream)

[Admin 2545]

,,for which antennas ... ???

[Admin 2545]

"So you need two MiMo antennas, one for 2.4GHZ and one for 5.5GHz...!!!

[zach.antre 0]

for 1 device i need:

1 omni antenna dual band vertical polarization

and 1  omni antenna dual band horizontal polarization

or

1 mimo omni antenna dual band (2x2)

 

for long distance device i need:

1 directional antenna dual band vertical polarization

and 1  directional antenna dual band horizontal polarization

or

1 mimo directional  antenna dual band (2x2)

 

I need different polarization in order to avoid intereferance.

If circular polarization have not this problem then I don't really mind.

But I think circular polarization has less distance

I do not know, you want a lot, why do not you look at this site, find enough antenna types...!!!

[zach.antre 0]

yes and that's why I posted them.

I just need your opinion on what is best for me.

Also this is the only omni antenna I found

http://qrzcq.me/do5ssb/Antennas/Printed_and_Microstrip_Antennas/Dual-Band_Meander-Line_Antenna_2.4GHz_5.4GHz.gif

do you have any other suggestion?

 

regarding the others, which gives best performance/gain?

 

[Admin 2545]

I think it's best to use two of them...

 

,,,or this...

 

 

[Admin 2545]

,,,or maybe it's better so,panel with two-band antennas...!!!

,,,but without omnidirectional polarization....!!!

 

For which this panel antenna could be for the frequency range of 2.3-2.6GHz ... ???
