Patch Panel 3G

[Admin 2581]

Double Patch Regular Polyhedron

 

The rectangle 94*68 mm, the sides of the cutting plane 28 and 16 mm rack Diameter 6 mm.
each patch has an input impedance of 100 Ohms, between 0.5 *Lambda of the connecting line. Obtained by parallel connection of 50 Ohms.
And cool chart SWR
the broadband is a patch in the form of an pseudo- ellipse with eccentricity 0.8, 2 Patches of narrow-band, but with the increase of the gap band of operating frequencies increases at 0.1 Lambda reaches 10/11 %. When band gaps, increases the ability of multi-mode excitation. With the increase of the gap increases and the value of the input impedance.
Based on this information, can built a patch with a gap from the reflector is 15 mm.
The line length is 0.5 L, so its width is not critical. In this project its width is about 2 mm d = 1 mm
The gap( between the surfaces) 15 mm width  to reflector Conn. line 13 mm.
the distance between the two coherent emitters choose, usually based on two criteria. Or the maximum gain, then it's 1 lambda or a little more. Or at a minimum side lobes, then it is less than lambda, about 0.7/0.8.

Very nice antenna.

 Yes, and you can post your version,four pseudo-ellipse( quadro)....!!

,,, with the dimensions in red, the antenna works on the frequency 2050MHz...???

 

[Admin 2581]

This is the site where I developed this antenna...

A new UWB panel antenna with 2 patches and 2 rectangular directors for the 2.1-2,55GHz frequency

and with the lateral wing version...

 

[Guest]

,,,are these reflector sizes good...???

 

[Admin 2581]

Adaptation line dimensions

[Admin 2581]

 

,,,for Guest...

dimensions gauge reflector

With such dimensions of the reflector it is possible to be such an antenna gain

Practical realization of a friend,,,

 

this work is performed by ...

I think this is an ideal double-patches form of antenna...

[Admin 2581]

"at user request, sa3500, I tried to optimize this antenna ...

[Admin 2581]

,,, what do you mean 85% ... ???

[sa3500 21]

I completed the antenna almost. 

85% - work done 

 

[Admin 2581]

"Well, then everything is okay...!!!

[Admin 2581]

"And here's the sizes ...

 

,,, for the adaptation line, the copper wire with a diameter of 2.6mm

 

[sa3500 21]

ОК. Thank you. I think I'll post a photo tomorrow

[Admin 2581]

,,, the formidable work ...!!!  and how does it go ...?

[sa3500 21]

It showed a slightly worse result than this antenna:

 

Later I will try to put the dielectric between the plates and remove the bolts.

[Admin 2581]

,,,it's normal to have a slightly worse result, it does not have 4patches...!!!

,,,the dielectric changes its dimensions and has little influence.

I will try to make such an antenna with 4patches.

[sa3500 21]

And on this antenna you can put 8 patches? Or it will give nothing?

[Admin 2581]

I think it is possible, and it increases the gain  to 18-19dBi...!!!

[Admin 2581]

 

[sa3500 21]

Yes. Wrong. Noticed only after soldered
