Antenna with wire elements

[aurel 22]

What you think about this shape?

,,,this is the last simulation of the zig-zag antenna...!!!

 

 

[aurel 22]

Thanks

So it is not 19 dB than maximum is 12 dB 

let say little bit less than double - biquad which is 14 ,,, i think ..right?

[aurel 22]

I just cut the Cu wire but i use 2.5mm2 - ordinary electric cu wire which is 

wider so maybe i get better results..who knows.

anyway antenna is easy to build...

Do you can simulate ...design i show in the image above?

if is not problem ..i don't have that CST program.

20dBi, got with four such antennas...!!!

with the dipole side = 57mm

,,,why this antenna does not work ... ???

Yes why...bad design probably...

I don't understand this diagrams very well but i see f= 2.2  not 2.4ghz 

is that mean something?

[aurel 22]

Is there any other freeware program which can replace CST maybe ?

i mean for wire antennas?

Auuu

that one was lame...

I found on source forge program called VEMSA3D but i don't know how to work with it?

[Admin 2545]

,,,this program is for linux...???

[aurel 22]

No i download it from sourceForge

you can find it there...

[Admin 2545]

,,, this is not an antenna simulation program ... !!!

[aurel 22]

then what is it ?

[Admin 2545]

[aurel 22]

ahhh

it is attempt to create something useful

In fact - we can create wire antenna adding nodes but is tooo slow.

correction my amos 9

[Admin 2545]

Yes, of course...!!!

[aurel 22]

I found this image ..about printed wire 

sierpinski fractal

[aurel 22]

then is there a way to build this one ...

[Admin 2545]

Yes, as far as I remember, I have done this fractal antenna on a forum...!!!

[aurel 22]

ok

I found this antenna on some radio amateur site YU ..i think

and i don't get it why is connection point here where IS NOT maximum of current density?
