Good afternoon, give the antenna a good antenna for the 1800 MHz mimo 
Found 2 antennas on the forum:

1 - http://www.lan23.ru/forum/showthread.php?t=12671
But, unfortunately, not its size at the desired frequency, tell me who knows.

2 - http://www.lan23.ru/forum/showthread.php?t=10879
Could you tell me the thickness of the disc, can I use galvanized?
In the drawing, the antenna of this size for the lower frequency 1747,5 pink color,
and upper 1842,5 green. Why, then, in the drawing there are dimensions in blue?

 

 

My answer is,,

it can build a patches antenna instead of a disks, a horizontal patch antenna group (at one end of the frequency band) and the other group with vertical polarization (at the other end of the frequency band)

this antenna also I need to try to make

But a little less frequency

how much?

на рисунке , эта антенна на 1747 и 1842

а мне нужна антенна на 1780 и 1870

[Admin 2545]

«Хорошо, но эти размеры для моей антенны очень хорошо подходят, 1780-1870 МГц VSWR <1.2

[chilanzar2 85]

Also a good antenna! Only gain a bit small.

[chilanzar2 85]

Jomy, the size of the square patches good? You have to have these patches autocad

[Admin 2545]

ok Erkin, but I saw you know how to work in autocad, it's simple, it's just rectangles patches ... !!!

[chilanzar2 85]

но, есть два размера, например  а 77 78,   а1  67 68.  Я этого не могу понять

какой размер правильный 67 или 68 ?

 

,, but, there are two sizes, for example, a 77 78, a1 67 68. I cannot understand this

what size is the correct 67 or 68?

[Admin 2545]

"There are two pieces of each

one for the 1720MHz frequency and the other for the 1840MHz frequency

[chilanzar2 85]

[Admin 2545]

I like it, when you make a test of it?

[chilanzar2 85]

[Admin 2545]

it does not see too good ... !!!
what do you mean with 1 patch...??

[chilanzar2 85]

the bottom antenna with one patch gives a swr

[chilanzar2 85]

the antenna will work?

[chilanzar2 85]

the figure shows two antennas . each of them strengthening what gives?

[Admin 2545]

this is another problem ... !!!

the main thing is to keep up the real dimentions,,,!!!

did you make two antennas of different sizes?

[chilanzar2 85]

нет.....

[chilanzar2 85]

[Admin 2545]

Erkin, это два типа антенн для двух частот с их соответствующими размерами,,,

 

Erkin, these are two types of antennas for two frequencies with their respective sizes ,,,

 

[chilanzar2 85]

I realized this yesterday. Today, I will re-cut. Jomy, as I do with short feed connector?
