60 Ghz Antenna

[Everzone 2]

 dear alll

 

does someone know how to make a good antenna for 60 Ghz ?????

mikrotik has made 3 devices work on 60 ghz frequencyy 

 sxt sq lite 60

lhg 60ghz

wireless wire 60 ghz

((((max distance is 1km ))))

can we make antenna parabolic dish for 60 ghz ?

or patch with very small beamwidth angle ?

[Admin 2561]

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

haha i didnt understand nothing

just answer  yes or no can we make dish for 60ghz ?

and if you can send me photo or dimensions

 The 60 GHz-band antennas are not possible for an amateur...!!!

Can i make this way ?

the antenna small green board i will attach it to centre of dish and the small green board will be faced to small aluminium circle reflector  , so the small aluminium circle reflector will also be faced the big 

circle dish 

[Admin 2561]

,,,no,the small green board it must to  be in the focus of parabola...!!!

yessssssssssss that what im talking about the small green board i will make it in the focus of parabola  butt with 2 reflector  ( small aluminium circle facing the parabola )

,,,you can put the antenna on the back of the circuit(device)...!!!

[Everzone 2]

device on the right and the small circle reflector on the left .------> reflect to the parabola

exactly !!!!

can i make this with 60ghz ?

how much percent i will gain ?

how much more distance to ?

can i replace the dielectric cylinder in plastic tube in this case?

be cause im using the device patch

and the hyperbolic can be flat ?

i asked you a questions above 

respond on them and i will show you when i have answers about my questions

and i will show you the result of the build  !!!!!!!!

[Admin 2561]

,,,but I want to see what antennas you've built up to now....!!!!

freq 60Ghz not for long range
but 60ghz highest throughput

[devton 27]

the main problems with 60ghz is you can not use usual connectors...

i would use something like tiny cantenna as feed for dish
