KSM...from where did you get it...???
-
,,,maybe so...

1. What factors affect the bandwidth, making it wider or narrower? ,,,, the distance between the antenna elements and their size 2. How is the feed point's distance from the center determined, and what effect does it have? ,,,, the feed point determines the frequency range 3. What is the reason for cutting the driven element? Why is it cut on one side or both sides, and why don't we use a full circular plate like the others? ,,,,, the marginal cut of the vibrator marks an elliptical polarization 4. Why 30 degree? ,,,,,for ellipticity 5. Can the rod be made from a non-conductive material like PVC or plastic? yes 6. What are your recommendations if I want to extend the antenna to 15 elements? go

OKAY, BUT THE DIMENSIONS SEEM TOO LARGE FOR THESE FREQUENCIES...!!!....150X130X65 mm ,,,or this....

,,,this it"s yours...
-
,,,unsolder the plugs from Ant1 and Ant2, and solder other plugs or coaxial cable in their place...!!!!

,,,NO...!!!

As I promised, I'll show you the results below...

Bow-Tie antennas aren't really Log Periodic antennas; however, the bow tie (or butterfly) antenna makes a good starting point to begin talking about Log-Periodic antennas. So we will first discuss properties of wideband antennas, and then discuss the infinite bow-tie antenna, and then measurements and properties of the real bow-tie antenna.

This antenna is an older simulation of mine, let's see if I can help you.

I think this construction is better..!!!
-
It's not good, what do you want to do..?
-
A smaller version would be better....

The fact that the antenna with several elements is very large for this frequency, I considered it necessary to make a reasonable antenna....

You have the dimensions....???

This is Patch Antenna for Controlling FPV Drones ....????

No, the purity of the copper doesn't matter...!!!
