I still don't fully understand it. How are the power lines calculated for such an antenna? Is it the same as for printed circuit boards, where only air is taken into account as a dielectric, or are different formulas used? Also, why is the element with the director bolted to the reflector at the centre of the element?
-
Wow.. How are the power lines calculated for this type of antenna? Is it the same way as in printed patch antennas? I also wonder why there is a connection to the reflector in the central part of the element. Is this a mandatory part? I just haven't come across such antennas before.

I have heard that steel is not good for high-frequency antennas.
-
This is stainless steel or sheet metal?
-
I got my hands on such an antenna, and I can provide the dimensions for copying.

Final version

Much better.

can`t open the file. I have 2024 CST Studio

Thank you

Made by myself

@Admin Could you help me with the simulation of this antenna, please?
-
Thank you so much!
-
Very interesting antenna. Can you give the dimension for 5645, please?
-
It can be used for 4G LTE as well as for controlling FPV drones

Copper comes in different grades: M00, M0, M1, M2 and M3. The grade is determined by the purity of the copper content. M1p, M2p and M3p copper contain 0.01% oxygen and 0.04% phosphorus. Copper grades M1, M2 and M3 contain 0.05–0.08% oxygen.

What if I build it using 1 mm M1/M2 copper?
-
Why? Because it is difficult to make it from a printed circuit board?
-
I made this anthenna and want to make it in PCB.
-
Thanks!

Is it possible to say that an antenna designed for 5645 MHz with a narrow frequency band is more efficient than an antenna designed for 5645 MHz with a wider frequency band? Thank you for the answer!

Hi. Can someone explain to me why you make the PCBs of the antennas like in the first photo and not like in the second? I'm new to this and I can't understand this choice.
