,,, it's still possible...
-
,,,for LINWLAN2,4GHz Antenna look at here : https://drive.google.com/file/d/1YUtCtA57I8AyKA4WGt4QRwAIShzAoUJn/view ,,,or maybe you want to do one of these...
-
,,,the two dimensions upper the red arrows(6:11)... ,,,on this site you will find enough antennas to interest you...!!!
-
,,,it is possible, but the isolation between the ports is not good..!!
-
VOVA, maybe you are interested in this ... !!! Vova0,75.cst
-
,,,biloop yagi on PCB transmission line...
-
,,, earlier I tried a panel antenna (mimo), but the isolation between the ports is not good...@@
-
,,,this skit doesn't help at all...!!! ,,,take this one...!!! Mavik2,4-5.cst
-
,,,interesting antenna for Dji Mavic/Mavic 2 models is highly advanced, operating in both 2.4GHz as well as 5GHz frequencies The concept behind the look of the antenna was to make it look like it was a part of the drone by default...
-
,,,,yes, but the shortening factor for the dielectric of the coaxial cable must be taken into account(k=0,6-0,8)...!!! ,,,different ways of connecting the repeater antenna...
-
,,,it seems that this antenna is quite good for 1,8-2,8 GHz band...!!!
-
,,,54,9mm...!!!
-
,,,yes, it is possible, multiply the above dimensions by k=0.5.
-
,,,for 75 Ohm impedance...
-
,,,yes, maybe we should..!!!
-
,,, these would be the simulations and dimensions...!!!!
-
,,how to build a flatband helix spiral...
-
-
LPDA 1,7-2,7 GHz
-
"Lunokhod-3 "(original, flight copy) ,,, the antenna (helix + patch), with all its long length, does not show a very high gain in directivity...
-
,,,directories D2,,,D19 can be 39 mm in diameter...!!!
-
,,,it's not exactly the best solution...try with wire mesh....!!!

Sorry, it's my mistake....!!! I will make a simulation with these dimensions(in red).
-
,,, as seen in the first post, it works best in the 2.6 GHz band...!!!
