Biquad Antenna

[Admin 2545]

,,,maybe this...

[Admin 2545]

That's it.
Has the PCB Measurement changed?

 

[efeksk 22]

Please send me the IGS file.

biquad2.igs

h=14mm

[Admin 2545]

yah

#PCB=1mm

[efeksk 22]

I will build tonight

[Admin 2545]

but this ,what's the matter?
 

[efeksk 22]

I do not understand exactly what you ask

This antenna is not good for you?

54mmx54mm

[efeksk 22]

I've never used. Which one is more productive

[Admin 2545]

I think the last one...!!!

[efeksk 22]

hımm. Denemek lazım.

[efeksk 22]

I have to test

[Admin 2545]

But with what antenna you reached 64 km...???

[efeksk 22]

We use 1.2 GHz system for long distance FPV flight. The distance in these systems is relatively more comfortable. It is much more comfortable because it is inversely proportional to the frequency. But the picture quality is worse than the 5800 MHz frequency. Also, in 1.2 GHz systems, the transmitters have more dimensions and weights. And the antennas are bigger. Quadrocopter is not a convenient frequency. However, long distance can be used in large airplanes. I am using a 1240 MHz Bi-Quad Antenna in the video receiver system for a distance of 47 km.

[efeksk 22]

Our 5800 MHz video transmitters have 600mW output power. With the best combination of antennas, a signal can be received at a maximum distance of 5 km. I've never heard of anyone going farther. But even 5KM distance is very difficult. Few people have reached these distances. So we have to design a good antenna

[Admin 2545]

I think in both cases you can successfully use such an antenna

[efeksk 22]

Owww. What is this

[Admin 2545]

Is 4x2 ring panel antenna =16dBi gain

Do you share this antebin building information?

[efeksk 22]

Yeah.
If the final design does not work very well.
I have not yet built a 1 mm pcb. I will give you information when I build it
