,,, from where did you get this image ,,, ??
-
,,,thanks Lhimo...!!!
-
Lhimo,more dimensions are needed...!!!
-
,,, look closer and you will find ... !!!
-
,,, because not all BS (Base Station) have X or Cross polarization..!!!
-
,,, yes, this antenna is good ... you can also post cst * files...!!! ,,, these are the frequencies for LTE...
-
,,, no, this is after the original version ... !!!

2x2 antenna panel, that has two polystyrene foam insulating spacers, being easily executed.
-
,, it is possible, but it is quite complicated to build...!!!
-
This type of antenna was developed by the "sgser" user...http://www.lan23.ru/forum/showthread.php?t=9279&page=49 The panel shows the elliptical vibratory elements which are fed by copper wire lines through a metal plate polyhedra...
-
,, and here is a simulation of the antenna with mine dimensions(I'll post them later)....!!!

Petra-9 turns into Petra-20 For the manufacture of a strong UMTS 2100 antenna, which it needed in a repeater gain circuit, must be used a small Antrax Petra-9 panel antenna. Petra-9 is used as a service (internal) antenna, but with a little refinement it can become an irradiator for an offset mirror.

,,,for tuning the 50 Ohm impedance,Total Efficiency must to be << -0,06 dB...!!!
-
I think I should test this mini-TV antenna...!!! ,,.from JM actualidades on YouTube...!!
-
,,,,a practical way to build this antenna...
-
,,,,ok, but these dimensions are not for the 430 MHz frequency ... !!!
-
,,,,it works in 2.4 --- 2.6 GHz....!!!
-
,,, well, this antenna panel is good,,,!!! ,,,but it seems that, this antenna exists on this forum....!!! ,,, these are the real dimensions ...
-
,,, for which the frequency...???
-
,,,please discuss in English ,,, in fact I will delete the dialogue in another language...!!!
-
,,, here is a simple and easy to make antenna, 16 dBi gain directivity,,,
-
,,,it works...!!! ,,,the patches are not isolated..!!!

Reflector 190x150mm on 2400 MHz but try to recalculate under 4G iota 2600, then replace the patches on the ellipse and see what happens, well, for the kit I will do and for 3G 1900-2200, if I suddenly buy According to the patch calculator dimensions 51. 2x38. 9 on 2600 and 200 ohm, 5mm-h (air) 45.2x38.9 2600-200-10(air) 48.8x38.8 2600-200-7(air) 44. 6x39 2600-200-7 (foam with a permittivity of 1.25)
