,,,,a practical way to build this antenna...

is it okay to use a 75 ohm connector on a 50 ohm antenna

By the way has anybody tried to put two FEEDs at 90 degrees on a regular dish (parabolic) ? (MiMo)...?

also puzzled by this question. I asked it to the admin in the topic about butwing

the thing is ...: how much shadow they cast (yagis need less area) (this bow-tie shapes need a LOT of REFLECTOR to work right...)

PS: i'm inclined to the PETRA designhttps://www.wifi-antennas.com/topic/478-petra-lite-box-home/#comment-3785...is amazingly smooth on ALL the bands...(but then again they need a lot of reflector AREA)

,,,no,this one,,,

 

Taking in account it's for an offset mirror, would having more directors improve anything? I've noticed there is the slightly bigger 3G antenna. It would be cool to reach more than 25 dBi gain.

,,, okay, do as you please...!!!!

I understand that it's about the system in a whole. The higher gain of the feed antenna doesn't mean better system when placed in the focus of a parabola.

If the reason why the simple Bester is better is not because it's easier to build, but rather it results in better antenna, I'll be happy with it. But if the antennas with higher directivity may help to achieve more gain in an offset mirror, the build complexity must not be an issue either. My experiment is about setting kind of a record for Bluetooth Long Range, so I really don't want to loose those extra 3 to 6 dB from the link budget if I can :-)

So which one is best, the simple Bester or the original Bester?

,,, good, but why not try to put a Batwing antenna in the focus of the  offset mirror...????

Why not? I'm open to any solution.

By the way, to me the Batwing antenna looks like a biquad modification. From the simulation data it doesn't look superior to the biquad though, except it has slightly wider bandwidth.

,,, watching this video, I considered it necessary to try to design a Bester antenna made of FR4 fiberglass....

,,, so I present below the simulation designed and sketches for making the antenna....

What is the advantage? Broder frequency response?

,,, if dielectric foam(polystyrene) is applied between the patches, the dimensions of the antenna can be reduced...

[jnkwqlqn 0]

Very interesting,,, !!!!!!

How do you think, would make it two sided with via stitching improve it in any way?

[Admin 2545]

,,, try and you will see ... !!!

[Admin 2545]

I considered that it is still necessary to ensure a uniform impedance over a fairly large frequency range, which is why  I came to this configuration of the antenna....!!

Bester antenna, made of spray bottoms...

 

[miloudsatdz 20]

It is difficult to find, especially a reflector piece

[Admin 2545]

,,,round elements are made of  the bottom of the cylinder for the gas cartridge (Butane-Propane) burner(outer diameter = 85mm)..!!!

4G антенна-LTE-это абонентское устройство для улучшения приема сигнала операторами беспроводной передачи данных, работающими в 4G (LTE 2500-2700 МГц).

hello JOMY. I read a sea of literature about this antenna, at 2630 there are different sizes everywhere, is your antenna ready for manufacturing? I asked you for a connector, I want to order several on ALI. I want to try to make two antennas. A cannon and a patch that we discussed and you gave the dimensions. And yet I don't really understand the place of powering on the patch. Probably stupid !!!

[Admin 2545]

,,, try to read this whole topic...!!!

,,, and try to use only English on this forum...!!!!

,,, this is the positioning of the feed points for the Bester antenna...
