Raul, if you have such an antenna, you can post a few details and dimensions ... ???

Design of Coil antenna
Coil inner diameter: 6 mm
Number of turns: 7 turn

Wire Diameter: 1 mm

Spacing between turns: 3 mm
 

Admin can you simulate this design in CST? I think this design is match to the wave vibration. 

[Raul 3]

Total oouter diameter of circle: 61.999 mm

Wire lenght : 747.687 mm

Raul, this sector antenna is very interesting, if you have one, I would be interested in more details and dimensions....!!!

Ok admin. I will make detail. Wait..

If one line charged can give 9 dBi i think every additional one charged can give 3dBi power. If we put five or seven charged maybe can make upto 45 dBi

,, I would like to see the connection lines between spirals and dimensions >>> !!!!

each unit 9 db

2 of those 12 dbi max

4 of those 15 dbi max

8 of those 18 dbi max

Under IDEAL conditions...(feed network. dielectric losses , mismatch etc)

up to  20 ...22...24 dbi is achievable on 2.4ghz (over a 1 meter area at 24dbi)...more than that is BALONEY...Bullshit...never seen...never happen

No i mean not that. 

Above is bad antenna. Very high vswr

I wonder, is it possible to reduce the back reflector width to 120mm, and how bad is the impact if I do so.

,,, try it, but don't post so many pictures...!!!!

[erossutrisno 11]

okay sir, I'm sorry

[Admin 2545]

,,, at the request of the user "Curb S. Gutter", I tried to optimize this antenna for a wider frequency band...

Where can I find such a dialectical polystyrene? Is it suitable in a building materials store? I'm sorry for the stupid question, as I understand it, you need a material with certain characteristics of dialectical permeability?
