,,, maybe it's something like that ... !!!???
-
,,, dimensions ... ,,,better like this....!!!
-
That's what the vibrator looks like...
-
,,, what happens if you combine a LINWLAN2 antenna with a Bester antenna ... !!! ???
-
,,, the dimensions are in the above simulation .... !!!
-
,,, it can work, but for what frequency in 4G .. ?? ,,,for this antenna you can give some dimensions ... ???
-
,,yes, it's true, the distance between directors and the diameter of the directors, it would be best, I think it is Lambda / Pi = 0,318*Lambda...!!!

(DTA)Double Triangular Antenna is one of the best zig-zag antenna. Her canvas in contrast to the previously discussed antenna differs in that instead of two rhombuses consists of two triangular frames. The antenna pattern in the horizontal plane with no reflector is an eight The input impedance of the antenna in the receive frequency range depends on the antenna dimensions and its forms, from the placement of terminals to which is connected a coaxial cable or other transmission train, and also the location in close proximity to antennas of different construction which influence the distribution of electromagnetic field in space. In this case, the antenna is in good agreement with the coaxial cable is 75-Ohm characteristic impedance without other adaptation This antenna is made by "com666" user.

The dimensions in yellow are for the 2300 MHz frequency...
-
,,, something like that, you can never say(3.5 x 3.5 = 12 (dbi)).. !!!!
-
,,,but anyway, I don't think that's the reality.... omni800-2600.cst
-
,,, yes, I think this topic was discussed on a forum...offset helicoidal parabolic antenna....radio vorticity:
-
I don't have these dimensions..maybe only by approximation ....!!!
-
,,, the vibrators are placed on an insulating plate or insulating tube PVC spaced from the reflector ... there are many solutions ... !!! The 50 Ohm impedance coaxial cable connects directly to the feed points.

Speak in English...!!!
-
,,, here you can find what interests you ... !!!

-
,, these would be the dimensions ... PCB material double plated FR4 #0.5mm
-
for which antenna ... ??? where is Harry36's original drawing ... ???
-
,,, there are a lot of antennas on this forum ... choose one ... !!!
-
Samir, only English is spoken here ... !!! ,,,for 75 ohm cable the only difference is h1 and h2...!!!
-
,,,what does the antenna look like ... ???
-
,,, yes, but I think the reflector is a kind of satellite dish...!!!

These are the dimensions for the 2.4GHz Bester antenna
