,,,according to the dimensions given by KSM , I did the simulation with the following results... ,,,it seems that this type of antenna is quite good considering the frequency bandwidth.

It was interesting to design a small and lightweight antenna from available materials for FPV. After looking at what is available in household stores, I decided to stop at zinc/brass for the antenna elements and a canister cover as a radom. And so everything is in order - as it seemed to me, a lid from paint cans / mounting foam / air fresheners is perfect for radom. Its diameter is 77 mm external and 84 mm internal. Height from 12 to 40 mm. Material-polypropylene. Based on this, the dimensions of the entire structure were selected. you will need brass / galvanized 0.25 mm thick, brass tube diameter 4 mm external (wall thickness 0.25 mm), screw m3 -40 mm. cap nut m3, SMA connector, pipe cutter, metal scissors, drills with a diameter of 1.4 and 3 mm. The reflector is made of sardine cans. General view of the structure and results:

This page details the construction of a biquad antenna. The biquad antenna is easy to build, and provides a reliable 11dBi gain, with a fairly wide beamwidth. an antenna geometry of ideal biquad...

In telecommunications, a collinear antenna array is an array of dipole antennas mounted in such a manner that the corresponding elements of each antenna are parallel and collinear, that is they are located along a common line or axis. Collinear arrays of dipoles are high gain omnidirectional antennas. A dipole has an omnidirectional radiation pattern when in free space and not influenced by any other conductors in that it radiates equal radio power in all azimuthal directions perpendicular to the antenna, with the signal strength dropping to zero on the antenna axis. The purpose of stacking multiple dipoles in a vertical collinear array is to increase the power radiated in horizontal directions and reduce the power radiated into the sky or down toward the earth, where it is wasted. They radiate vertically polarized radio waves. Theoretically, when stacking idealised lossless dipole antennas in such a fashion, doubling their number will produce double the gain, with an increase of 3.01 dB. In practice, the gain realized will be below this due to imperfect radiation spread and losses.

I think I was right....

60 mm not maybe>2*30,6+3=64,2 mm....!1!

I don't really believe it, but I'll do a simulation in this regard...how much distance(93 mm) do you want ...???!!!

That's it, what are you going to do with it?

4G antenna BDM-2 is a wave channel with crack initiation, and the delay line is made of sequentially installed disk elements. Compared to the classical antenna BDM , new directional antenna BDM-2 is: More gain; Improved radiation pattern; More stable operating parameters; Greater reliability; Superior mechanical characteristics. Due to the small weight, a small sail and streamlined shapes, the antenna BDM-2 can be used in almost any climatic conditions. And corrosion-resistant materials of the antenna will ensure a long maintenance-free operation even in the marine climate.

Clanon, the antenna could be one of these types.....???!!!!!

hello, maybe this will help you...you ONLY have the antenna for 5G... https://www.waveform.com/a/b/guides/hotspots/t-mobile-5g-gateway-g4

Antenna BDM-2 is designed for outdoor use, although often applied in residential/non-residential premises. Experts recommend the use of antenna BDM-2, as a client equipment in all cases, build wireless networks of small and medium-range. The original of the antenna is with a 64mm diameter cylindrical vibrator

1. What factors affect the bandwidth, making it wider or narrower? ,,,, the distance between the antenna elements and their size 2. How is the feed point's distance from the center determined, and what effect does it have? ,,,, the feed point determines the frequency range 3. What is the reason for cutting the driven element? Why is it cut on one side or both sides, and why don't we use a full circular plate like the others? ,,,,, the marginal cut of the vibrator marks an elliptical polarization 4. Why 30 degree? ,,,,,for ellipticity 5. Can the rod be made from a non-conductive material like PVC or plastic? yes 6. What are your recommendations if I want to extend the antenna to 15 elements? go

FPV batwing antenna 5.8 GHz 12dB 30° WavLink Batwing 5.8 GHz SMA, for quadrocopters and aircraft models-will allow you to transmit a radio signal wirelessly, more stably and over a longer distance. The presented directional antenna operates at a total frequency of 5.8 GHz and is mainly used for quadrocopters and aircraft modeling, in order to increase the signal transmission range. A special feature of the model is the high gain, wide bandwidth, collapsible design, good housing materials and a popular connection connector. The antenna is one of the best FPV antennas in its price range, as it has a good gain factor. The gain of this antenna is 12 dB, which is enough for most tasks. The antenna can be used to stabilize the signal and display the image accordingly. Most often, this antenna is used to transmit a wireless signal in aircraft modeling, and it can be used both on transmitters and on wireless receivers. The antenna has a simple design and a high gain, so the engineers of our store conducted a special test. We conducted the test with a quadrocopter and a 400 MW 5.8 GHz transmitter, as well as FPV goggles. In the first test, omnidirectional clover-type antennas were connected to the devices, while the video signal transmission range was about 150 meters. In the second test, the Batwing antenna attached to the boom was connected to the FPV glasses, while the video signal range was about 5500 meters. https://gadgets-world.com/fpv-antenna-batvynh-5.8-hhts-12db-30-wavlink-batwing-5.8ghz-sma-dlia-kvadrokopterov-y-avyamodelei/
