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

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

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

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