BatWing antenna 2.4 ghz

[clanon 237]

the slit horizontal means the antenna is emitting VERTICAL polarized signal you'll see it as 2 or 3 db of increment on the reception side (vertical dipole) LineOfSight no reflections (reflections might have ANY polarization)

[remio 1]

I installed the batwing on the remote control with a slit vertically, on the copter the reception is also vertical, it turns out I need to redo and install the farting slot horizontally .

Thank you clanon !

Hello everyone. So this is the best Batwing version for today?

and the option of power supply №2 and №3

1st

but the difference will be small and not the fact that it is particularly measurable

if I build it (which i WON't) I would pass the cable STRAIGHT ( NO angles ) from the reflector's CENTER and solder it from BEHIND...(but that's just me) need to simulate to confirm...Like i did on the parabolic feed...of course you need to fix the reflector without the bolt in the middle or make it HOLLOW

he is using 3 Different cable length in this antennas

so IF you try to use cable length from #3 type (best SWR on video) AND use this cable length with connection option #1 it will be the best

NON PERIODIC ( non resonant ) CABLE lengths shouldn't be a problem (only for signal loss , bad connectors, too long , bad quality losses)

it's just an interaction between the VNA hardware and the cable...i think...

CORRECT ME if i'm wrong.

only practice will show...but i still think: cable length from #3 on video and conection scheme from #1 is the best option

Batwing "folk antenna". At the end of the video, a test. 130 megabits issued in the basement in the room

Interestingly, and if 4 pieces of such batwing are connected together, how to match them?

,,, yes, on this forum you can find enough ways to connect 4 antennas..!!!

Does anyone have any thoughts on how to make a batwing mimo irradiator

Edited August 21, 2021 by Sl4va

[Admin 2530]

,,, maybe so ...

,,,or so...

[Sl4va 11]

But here the SWR is not very good at 1800 and at 2600

[Admin 2530]

,,, this happens at cross polarization...!!!

,,, but by changing the dimensions a wide band of frequencies can be obtained...!!!

[Sl4va 11]

I just need it for a frequency of 1800 MHz (mimo)

Does 1800MHz need a larger size?

[Admin 2530]

,,, of course, I will try to design a batwing antenna around this frequency...!!!

,,, you can make something like that...???

...1 Crossed Dipole Batwing Antenna

[Sl4va 11]

The antenna turned out to be very beautiful. And what are its dimensions?
P.S. And if you put it in a cup (cut bucket)?

[Admin 2530]

,,,what bucket do you have ... ??

,,, some dimensions for buckets...
