"Anyway, you have to know that such an antenna does not have a good isolation between the ports (P1, P2)...!!!1
-
,,,,why do not you try to adapt the old antenna by doubling it ...???!!! But it's usually like that...
-
"if I said 15dBi, then let it be ...!!!

,,,okay,this it"s... Kharchenko antenna for 4g modem with your own hands Called the device by name of the engineer who first came up with it. It is a powerful external antenna for usb modem 4g made with his own hands, the schema for the required option can be found in the Internet. We present the easiest. All the parameters are calculated depending on the frequency of reception and transmission of the modem. ll the parameters are calculated depending on the frequency of reception and transmission of the modem. The calculator can be found here. http://www.texnic.ru/tools/gl/gl002-1-1.html "Soon I will give the calculated dimensions for double-biquad 1800MHz, with the side of about (0.375 ,,,,0,55)* lambda...!!!

Yes, it's real this gain in directivity...!! "But it can be so ...
-
"No, you do not have to buy an SMA, just unzip the plastic case from the antenna SMA...!!

-
,,, here you find a lot of programs for WiFi....
-
,,,good, it's very good ...!!!
-
,,,you can do instead of 110mm to 95mm , but the gain in directivity will be lower....!!!
-
-
I think this butterfly shape is better...
-
,,,good, and here we have the simulation results of these antenna...
-
Well, congratulations,,, !!! ,,,but with the antenna of the wire how many TV stations did you catch....???
-
AGATA-2F 4X4 MIMO Constructive details of the antenna...
-
,,,missing director and reflector....!!!
-
,,,good...!!!! ,,,yes, it is possible...!!!
-
I guess it is useful to replay REMO versions of this antenna to which the connection is made by coaxial cable... ,,this solution does not have a uniform impedance across the frequency bandwidth...!!!
-
,,, a model much easier to build...
-
Well, but the antenna has nothing to gain in the directivity 16dBi , as they say...!!!! ,,,,patatua666, where you found this drawing...??? Panel 16dBi 5GHz 56x57mm
-
That's what you ask me...!!! Material = Aluminum #4mm Isolated Spacer= plexiglass 20x25,5x40mm
-
,,, I think it's a better option...0,5...0,7GHz(200MHz bandwidth)
-
,,,to solve the problem with isolation between ports, it is necessary to execute a cross-cut to the vibrator and to place an insulating spacer...
-
,,,it"s good...!!! Tell me, are you taking the test today?
-
,,,yes...!!!
