This is the simplest type of antenna from a theoretical point of view.

Is it dipole antenna ?

,, so, a dipole antenna is made of a single piece of metal strip by successive bending ..!!!!

 

 

[Admin 2545]

and now ANIMATION ..

 

[Admin 2545]

,,,with a radiator 1x110x110mm, increases in gain and directivity of the dipole...

 

 

,,,and a sector antenna with 4 dipoles

 

[Admin 2545]

,,, and this is an older version of my...

 

[Admin 2545]

From a gas cylinder bottom, you can get a parabola for this dipole antenna wifi

[Admin 2545]

Another dipole antenna version with parabolic reflector...

 

 

,,,or so....

Hello Admin,

a few days ago I decided to have some wifi experiments at home and found your forum with all these information...wow! I'm not experienced and have few tools to work with, but I'd like to build some of your projects.

Is it possible to build this antenna using thinner aluminium foil like beer or cola can?

Also can you please recommend me which cable and connector to use and where to buy: ebay, mouser..?

Many thanks

Lorenzo

,,, welcome Lorenzo ...!!!!

,,,yes it is possible, but tell me how you weld the aluminum ... ???

,,,you better use the tinned sheet from the cans...!!!

You're right, I can't  

I'm not sure I can weld iron too, I just have small weller with 80w iron, is it ok? Otherwise is it possible to build the antenna using screws to lock the wires?

Please excuse me if I'm having stupid ideas, it's all new for me

[Admin 2545]

But tell me what kind of antenna you want to do...???

I'd like to build an indoor antenna with low gain but wide angles like this one, and two directional to make a point to point link to my grandparents home.

The simplest the construction, the better

I have tv antenna cable, solid copper wire of different diameter and some nice hard disk platter that i can reuse, could they be useful?

I also have a few rubber duck antennas from old access point I can disassemble

 

[Admin 2545]

,,,hard disk platter  can be reuse it, but I think only for the biquad antenna, as a reflector

 

 ,,,rubber duck antennas it is easy to disassemble, slightly heated...!!

[RanocchiO 0]

Ok, which projects do you recommend for my purposes? Is this one ok?

Which are the ones more tolerant to construction imperfections  (considering this is my first attempt)

Thanks

[RanocchiO 0]

Yessss

Is it this one?

 

[Admin 2545]

,,,well, then on this site you find everything that interests you ... !!!

[Admin 2545]

Different forms of dipole..

,,, and a simulation of one of them...

[Edel2020 20]

It really looks simple....what design to do to get closer to 20db at about 20 km in band 3 1800 MHz?

[Admin 2545]

,,, this would be about the frequency of 1800 MHz...

[tomasbj 5]

Very simple and intersting performance. I guess Circular Pol will work well too by using two of these orthogonal oriented and 90º phase shift. I wonder how to make this much smaller. for the same frequency band. 

[Edel2020 20]

So...can we add directors? Would it work as a yagi?

Wire grill  (big 80 cms at least) OR parabolic dish EVEN BIGGER 1.2 1.5 meters

Parrilla de alambre  (grande 80 cms mínimo) O plato parabólico AÚN MÁS GRANDE 1,2 1,5 metros

Clanón... can you help me with something like this for 1800 mhz, I thought about making the Yagi Extreme lll ...but no one has simulated it or confirmed the gain and how good it is
