,,,hi buddy...!!

,,, can you give constructive details ... ??

[Harry36 140]

Hi!

cst2021? ок?

,,,yes,it"s okay...!!!

,,,this is you...??

do you have doubts that they are not true?

,,,it is a very good antenna but it should have a wider bandwidth for the 50 Ohm impedance...!!!!

This antenna has been modeled for maximum gain, and low VSWR  in the 5.6-6 GHz band. real bandwidth by WSWR <2 4000-6200 MHz (5G + WiFi 5 or 6 GHz). You can change the bandwidth in the Simulation -> Frequency section, and also add the rendering frequencies to the History List in the first paragraph by editing it.

SLOT half wavelength radiator...? 

It would be nice to put 4 or more and feed it with a PROBE...

Yes, Boss

thinking of making a grid of 4 butwing? I am confused by the size of this design for such a range: (the size of 4 elements will turn out to be 200 * 200 or more (you need to look at the side lobes), and the gain will be 19 dBi at best.This antenna is already on the verge of rationality (more than a pack of cigarettes). At the beginning of the topic there is a patch in a metal plate, it has a gain of more than 15 dBi

With these dimensions, I have only one idea - SMA on the back of the reflector + balun from a 3-layer PCB (FR4).

What do you say, friend?

LOSSES...and 5.8ghz is a BITCH on CHEAP PCBs...

PS: i was thinking on a box , thin edged , with 4 slots in phase and a probe quarter wave feeding the whole thing...ALL METAL...

Simple antenna with small dimensions and 12dBi gain for FPV (5600-6000 MHz). Circular Wave Polarization Antenna (RHCP).

bonus: wi-fi 5150 - 5825.

Bu programı kullanmayı öğrenmem gerekiyor.

Nereden başlamalıyım?

I need to learn to use this program.

Where should I start?

 

[Admin 2545]

,,, what program, for simulation or for measurement of antennas ... ??

[Harry36 140]

[Admin 2545]

,,, it seems that the impedance is not very good ,, okay, okay, it also shows the dimensions .... !!!!

[Admin 2545]

,,, what is ... 38 * 38 * 6mm steel...???

I bought an Antenna from TrueRC 1.2G for video. fly the plane. Broke during use. I ask for help. Is it possible to repeat the manufacture of the antenna at home? Thank you

 

[Aksonx2 13]

Please tell me if there is a calculator or model. I bought for video such an antenna at a frequency of 1320 MHz. Is the structure assembled correctly? During transportation, I bent the matching line a little, what distance should be from the reflector? An image of such an antenna slipped on the forum but lost:)))

,,,hi buddy...!!!

,,,can you give some dimensions to these antennas...??/

,,,you forgot the diameter of the patches and the wire...!!!

,,,вы забыли диаметр заплаток и провода...!!!

sorry!!! diameter of the patch 125 mm, diameter of the wire 1.5mm

[Admin 2545]

,,,okay, I will try to do a simulation of this antenna...!!!

...the input impedance is 50 Ohm...???
