What is the working frequency of the base station (BS) that you want to work ... ???
-
", okay, but I do not understand what you mean with this YouTube ... ???
-
,,,for 2100MHz...
,,,this it"s the antenna...
,,,,IMPORTANT...!!!
,,,at this antenna the power pin of the vibrator has a diameter of 1.737mm and must be made practical...!!!!
-
,,, no, this is from your pdf file...!!!

I can't open this file...!!!
But the simulation, is clearly, not correct...

Andrew, please show me, where you found this...???
-
,,, another variant(MiMo) ...

,,, and a few more pictures with details about the impedance adjustment lines of antenna...

,,, and a variant proposed by the user "com666"...

In fact, nothing new has come up, just connected the methods of powering the two ports, the outcome is greater than -20 dB throughout the band, wide band SWR.
The antenna is recommended to be used in the focus of a parabolic offset disk.

,,,okay Nikram77,,, if you manage to order PCBs, you can send to me some pieces...???
,,,,this is *gbr file for pcb FR4...

Test comparison of antennas for the Internet from 'Anteks' & 'Gellan'....

Yes, it seems that I had a mistake in the design, now it works,,,
,,here it"s the modified CST*file....!!!!

3 minutes ago, RC-Concepts said:After PCB A and B are aligned, you mean VSWR is still 6.74 in your simulation? This is strange.
,,,, yes, you're right, that's what I ask myself, why ... ??? !!!

Or maybe you want to say something like that.,,(dual frequency=814MHz-2442MHz)

,,,or something like this...

My simulation above is compliant...!!!
How long is the coaxial cable ?, this is important ... !!!
-
,,,for this frequency band, I don't think it's possible...!!!
,,,maybe only a Vivaldi antenna....!!!

,,, a first test with wire mesh, with 10mm mesh( without reflector)...
,,,with reflector...
