,,,for which type of antenna I tried an optimization to increase the bandwidth ... ???
-
wifislax64-2.0-final for download...https://foro.seguridadwireless.net/live-wifislax/wifislax64-2-0-final-para-descarga/
-
,,,for which this antenna was simulated ... !!!!
-
,,,and now let's see how this antenna behaves...
-
I do not really understand what you want...??? ,,,what is 120d...???
-
Good results can only be achieved if used in suitable PCBs, in any case not FR4...!!!
-
,,,but I want to see what antennas you've built up to now....!!!!
-
,,,until you make such a "jewel", show me what you have built so far in this field of antennas...!!!!
-
,,,good, that's another fish food...
-
-
,,,you can put the antenna on the back of the circuit(device)...!!!
-
,,,no,the small green board it must to be in the focus of parabola...!!!
-
After several attempts with different antenna variants, I've come to that....MiMo Panel Antenna But it must to be optimized...!!!
-
,,,good, now I'm working on this antenna ....!!!
-
I will try to do this simulation...!!!
-
,,,okay....!!!!
-
,,,the thickness of PCB....??
-
,,, and the thickness and distance from the reflector...!!!
-
For such frequencies, the material from which the PCB is built, matters a lot...!!!
-
The 60 GHz-band antennas are not possible for an amateur...!!! http://wlan.am/en/point-to-point/176-wireless-wire-dish.html

A highly directional antenna, even at 60 GHz it is not problematic to do, because the focus and aperture is related mathematically through the square of the wavelength. A = D / lambda^2 / 4 / Pi A=aperture efficiencies D=diameter of parabola In terms of the parabolic mirror with the efficiency of the use of the aperture efficiencies 60% (very good feed) Aperture efficiencies of typical antennas vary from 0.35 to 0.70 but can range up to 0.90. Dimensions of above parabola Ø 391 x 222 mm

,,,good, I think this would work ...
-
,,,the antenna can not be so small ... how can it be PCB = 1,5x14x46mm ???
