Biquad Antenna

[efeksk 22]

If you want to start this hobby, you should microquadrocopteral. Can be flown both indoor and outdoor
Also, the risk of breakage is small if you are small and crash.
I will write you the materials you need, my friend.

I will never forget this goodness.
One question....
Do you use the CST Studio program for antenna design
It's really a great program. I would like to learn a lot

If you know SolidWorks, it's very easy to learn CST Studio

[efeksk 22]

I know solidwork well. I will download cst and dig it. I think cst lessons are useful for forum

[Admin 2545]

And the other variant,,,

[efeksk 22]

 

Dude, you are absolutely perfect. I built the first Antenna and tested it. The results are great.

[Admin 2545]

try this...

Igs file!!!

[Admin 2545]

Another solution you can not find ,,, ??

No metal screws,,,!!
Put insulating spacers ... !!!

Efeksk, can you tell me the dielectric constant to FR4 you have?

[efeksk 22]

dielectric constant = 4.47

[Admin 2545]

I have taken dielectric constant= 4,43 ,,,, maybe this is the difference...!!! but I do not think too,,,!!

[efeksk 22]

No. Already on average between 4.25 and 4.60. Such a small dielectric constant does not affect the frequency.

[Admin 2545]

"Then metal screws are to blame," !!!

[efeksk 22]

I would like to manufacture this design with fr4 of 1mm thickness. What about you?

[Admin 2545]

,,,no,try without metal screws ... !!!

[efeksk 22]

These measurements were made without bolts.
I will send you measurements made when you have bolts

Then everything changes...!!!

I will try this option too, !!!

[Admin 2545]

[efeksk 22]

Why did the values change?

[efeksk 22]

Component specified as abs.
FR4 Epoxy material. It's very different from plastic material. No choice between epoxi options

[Admin 2545]

,,,see this...

[efeksk 22]

Oowwww. 

Ok

[efeksk 22]

Which antenna is more effective at 5800 MHz frequency over long distances
