Antennas for Drones

123 posts in this topic

We see what the antenna design is slightly modified based on the experience in the manufacture of the prototype was made a specific allocation of matching elements and active elements themselves. The concept remains the same.

No, my friend
This is a variable option.
First you need to set the size of the dron and its purpose.
We will then make a list of engine esc and other equipment

Wooww
It looks good.
But for better work, try to make the angle at the extreme point 25 degrees instead of 45 degrees. And the tips at the top of the arms must be 25 degrees outward. It must also be 25 degrees outward at the ends of the arms facing downward.

Moreover, the parabolic reflector on this wheel will be useless

No this is not good. He's using a brush motor system. Brushless motor system is better

What kind of antenna ?

 

Made for 2.4 GHz and 5.8 GHz frequencies. There is a reflector at the back of the tee. Could you work that way and build an antenna? For a 5.8GHz remote controller and a 2.4 GHz image receiver
