BatWing antenna 2.4 ghz

258 posts in this topic

If the Batwing emits horizontally polarized radiation in the horizontal plane, then how to position the antenna vertically or horizontally with the slit, if it is transmitting, and there is a dipole at the reception, which is now vertical, can the receiving dipole be placed horizontally more correctly?

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)

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 !

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?

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

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

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

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

Does 1800MHz need a larger size?

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)?
