Tsar Cannon 4G Antenna - 1700-2550 MHz VARIUS

[Admin 2811]

The 4G LTE MiMO 2x2 Tsar-Pushka VARIUS antenna differs significantly from conventional ribbed-rod "pushka" antennas in its wider frequency band.

While conventional antenna guns can only be designed and manufactured for a single frequency band, the Tsar Cannon Varius antenna model works perfectly in the 800 MHz band from 1700 MHz to 2550 MHz.

The Tsar Cannon antenna can be used on the following bands:

Band 1 (1800 MHz)
Band 3 (2100 MHz)
Band 40 (2300 MHz)
Wi-Fi 2.4 (2400-2500 MHz)

The antenna has excellent cross-polarization isolation, which allows the MiMO 2x2 technology to operate as stably as possible.

Maximum antenna gain of 11-14 dBi 

The Tsar Cannon antenna has a pronounced radiation pattern.

The antenna can also be used in the 2500-2700 MHz band (Band 7, Band 38), but the gain will be low and the SWR will be high. We recommend using this antenna in these bands only in extreme cases when there are no other options available.

The antenna is interesting but it still needs work, it doesn't have a large bandwidth,,,only 1,8----2,2 GHz

 

[clanon 323]

you COULD try with triangular elements

they build it like that (two flat stamped sheets) for easy manufacture and cheap...

Yes, I think it's a good idea, but there are problems with impedance matching....!!!

,,,maybe a circular parasitic patch should be added after the radiator...!!!

How should an antenna be designed to increase SINR values?

[Admin 2811]

If your SINR is quite decent,you can use a small 0.55 dish with an irradiator, as the signal strength allows. As for the speed instability, it largely depends on the provider and the load on the base station. The more users connected to the tower, the slower the speed.

If noise is fix you increase SIGNAL = GAIN ...(adding directivity will also lower Noise from  out of the main lobe signals) a bigger reflector might be enough

Jomy ,could you post the aproxímate dimensions...I wanna try and make it wider bandwidth)

[Admin 2811]

I don't know if this can help you.....

 

[clanon 323]

I'm goin to replace the squares with bowtie triangles to check if it gets better...

do you have the N type connector posted somewhere...?

[Admin 2811]

,,,does this suit you...??

Company published VSWR

A little more bandwidth with the Proximity FEED TAB (instead of direct contact)But yagi bandwith is real limited...an NEW whole band Bow tie LPDA would have better bandwidth...

[Admin 2811]

[clanon 323]

Proximity feed (quarter wave Lambda) Widens the bandwidth impedance...a little

I didn't like mine , if YOU want to tweak it , WORK over the feed tab size and distance to optimize the impedance bandwidth

,,,2.1---2.5 GHz, is the frequency range quite good...???

[clanon 323]

Directors EXACT size might matter and distances between them...Should look like this...

I think this connector is used on the Tzar Antenna....
