This is probably the clearest explanation in UKposts of how antennas work.

This is an amazing video!!!! I've been working in IT for years and I've seen the charts for the antennas I've used in the past, but never really understood with clarity what they meant. This was immensely helpful.

The animations used are really good, as the whole video. Well done!

the best explanation with absolute clarity

Thank you for such a nice video about antenna , animation , audio quality and voiceover , are very good. Learning or knowing the " mysteries of radio " , and science was never so easy before. Jazakallah.

Keep up this good work!!!I would love to watch more upcoming quality videos...I have subscribed already now because of the quality of knowledge of concept that you provide through your videos.Thankyou so much!!!

The video is great. I have been in the communication tower business for over 20 years and don't know any tower dog that knows this. 😂. I own and operate a small communication tower contractor and mainly install equipment for Verizon and AT&T. I want to use this video for training purposes in the future.

TRULY a great video. Thank you for this. It explains what is in my head, but I cant relate to my friends. Well done!

amazing video, I'll show this to any new student of antennas!

I'm a physicist, so not much new knowledge to me, but very good animation and didactic way of presenting the subject. Thank you for the effort and letting people get acquainted with this huge topic.

Yo, this is god-like material. Thank you! Can’t believe it’s free!

Thank you for fixing the audio. Great video 👍

Nice animations. Fine primer for people who aren't in electronics. Electronics brain is asking what about the analogue of space as a transmission medium with characteristic impedance, as with any other transmission line, and how impedance matching is important, and how the length of the antennas are usually a bit different than calculated due to the self inductance of the transmitter... Reflections. Noise. Side bands. Near and far fields. These are just off the top of my head. Nice animations. I'm not complaining. But I have been searching for a long time to see a good video describing near and far fields and lossy transmission lines. I want to learn more of that in like granular detail. There is some tech I worked with, long ago, and now I wanna know how it worked exactly. The work was for a communications company in the Arctic (a weird place).

Engineer, Your work is an excellent

Thank you for such a nice video about antenna.

Now the audio is perfect

Excellent lecture Sir. Thanks 👍

Outstanding video! Thank You a lot! ❤👍🏻

This is pure gold ❤

I learned so much from this. Thank you for sharing this wonderful knowledge :)

Excellent informative video thank you

Drawing of a radiation pattern of parabolic antenna was a hard nut to crack during a class of antenna theory back in those days.

Thanks. That was helpful.

This is quite intuitive

AWESOME VIDEO - - EXCELLENT WORK ! 😎👍👍

This video helps me understand the way the energy fits into my understanding of how I work the universe works, black holes work and all life works because all actions works and have the structure of a donut. I can feel energy radiating from people with my palm chakras it was the hand shape they used to describe the electrical energy which helped me understand if energy is going in or coming out of the body

Thank you for the video.

Excellent education ! 👌👌

subscribed, really it solved my many queries an amazing video

I'm so glad this video exists. I use to completely not even understand how antenna worked, and now I still don't 🙃

Actually the method by which "radio waves" travel is photons. Alternating charge acceleration (voltage) in a metallic object produces photons as the electrical charges expand and contract just like doing the same produces light via mercury atoms in a fluorescent lamp. Radio reception is achieved when the photons interact with metallic objects and turns photon absorption into expansion and contraction in the antenna, thus producing a reverse of the alternating charge acceleration in the transmission mode. Charge acceleration is detected and the alternating voltage amplified, processed and the output turned back into meaningful information.

非常感谢，受益匪浅

Great explanatory video.

Thanks for one more amazing video.

Well done!

Super cool video! Thank you! 🙂

Well-Done

Amazing

What software can be used to make this animation?

I think it important to note for the uninformed, depending on proximity, just how small these signals moving from a transmitting antenna, to a distant receving antenna are ! And the important role the radio receiver plays with it's amplifying abilities, which without those amplifiers, these weak signals, typically could not be rectified, and heard ! Too, something I don't believe was mentioned here, is the, " Law of Reciprocity " ! Which simply states that an antenna used for transmitting, will also exhibit the same characteristics, when used for reception of radio waves ! Essentially, the antenna will work equally well for both, transmitting and receiving ! Also something known as resonance of a given antenna, plays an important role on how well both transmitting and receiving work. Much like the tuning of a Guitar, or other stringed instrument being tuned to produce a certain pure note, due to vibration, which in turn is frequency, the antenna must also be tuned for proper operation ! 🤔....? Just Say'n !

I think it's just MAGIC !

Great logical deduction. Well done. But, I still haven't seen an explanation of what is happening at a molecular level. ie, why does pressure decrease when are is blown over a hole, like in a carburetor?

Very impressive. I subscribe.

Brutal Video! Video with Indian accent level

thank you

Thanks 🙏

I am a little confused with the difference between magnetic fields,electromagnetic waves, and where photons play into all of this. I thought we used electromagneitc waves to communicate information but in the video I think its describing a magnetic field with Amperes law?

Thanks

I'm trying to become a patreon but probably the link on your UKposts page is not working, and I'm struggling to find your name on Patreon's website 😕

What was wavelength? I don't get it. And why are the egdes of monopole antennas causing more intense light in a luminescent bulb than the center of antenna? If we put a bulb next to these antennas?

wavelength is horizontal, both antennas are vertical, the only way this would work is if the vertical amplitude is always equal to wavelength and this has always been my question which no video has answered, because the horizontal plane is time related.

Electromagnetic theory is just amazing

12:10 What is it exactly that "bounces off the dish and is transmitted into space"? How is it transmitted? What is the dish made of? What is space?

Nothing new, but nicely presented. Maybe mention why electricity seems to ‘jump’ from the wire to the ground, the dielectric effect. Same effect as the capacitor. So, that’s why you can pump electricity into a strand of wire and it gets absorbed.

Nice

around 1:26, u showed the right hand rule, does the hand rule use conventional current flow or electron flow??

A question, on the video the receiving antenna is vertically positioned, while the electric field is horizontal. Shouldn't the antenna also be horizontally positioned for best reception?

One has to know atomic theory. How can the electron (a sub-particle of an atom) move from one place to another? Knowing, and that electrons are both particles and waves, along with Amp's and Faraday's laws, antennas can be understood.But first one must wrap their head around electron theory. (Rachweston's comment here in the comments section better explains what happens)

Sir what is the name of the software used to make this video please😊

Just some feedback 😅 the thumbnail says: "how they works" work* just a typo but I let you know 😄 4:58 no we are NOT moving away from the main topic (antennas) because that's how they work otherwise is only a piece of metal xD

Did u know about vivaldi antenna ?. Now its used on military aircraft radar

Master

If current flow in the same piece of wire wouldn't the current short circuit out?

It was mainly correct. But cell tower without a single cell antenna? :)

What about phase arrays? Lol great video!

7:01 i think it's called spherical coordinates, correct me if i'm wrong

The director elements on a Yagi do not amplify, they focus / concentrate. See End Effect.

No mention of loop antennas? I think most of us have seen them with radios. Be nice to get an explanation of those and how they differ from other forms.

❤❤❤

Sorry but despite the general concepts being accurate, this explanation is misleading as it makes it look like local magnetic filed is the same as the magnetic field of the wave. They are not the same. The magnetic field fades very quickly form the source so I would never be able to influence a remote receiver. It is the electromagnetic waves that can actually propagate. This a subtle but crucial difference

👍

👍👍👏

Can you explaine me how smartphone antenna works ?

Is my phone strong enough to transmit signal to cell tower? As cell tower transmit to my phone..

No mention of what happens when you have two antennas radiating same signal near each other.

1:50 Induced electron movement is is going in the wrong direction

Antennas darkest medak Red Gold its perfect

I was expecting for some 3D wave patterns of the different antennas, instead we're only shown the 2D graphs.

👌👌👌🙏🙏🙏

An antenna isnt a closed circuit though. Im still confused.

5:45

Mau buat antenna settelite for Anttena Di bekas numbur arwah ,depan kedai Rita Enterprise,Kg,Kiambor,BAKARO,Kuala Penyu,Sabah.

God says when the bees gone the end is almost here

❌❌❌Warning: the electromagnetic wave in this video is wrong! ❌❌❌ The most useful part of this video is the portion from 3:21 to 5:22, where it shows how an alternating current can induce a changing magnetic field, which in turn induces an electric field that can move charges and create a detectable potential. This video would have been a wonderful resource to help people understand electromagnetic waves, since most if not all other animations online use electric fields as the primary entity, with magnetic fields just tagging along for the ride. Unfortunately, this portion of the video is also wrong: the induced electric field and motion of charges should be in the opposite direction to that shown in this video. It is easy check this because electromagnetic waves propagate in the direction of E x B, which is opposite to the direction of propagation shown in this video. I hope this error can be corrected before some poor student flunks their physics or engineering class because of this.

I'm here because I'm experiencing an interference on my TV antenna and modem antenna 🤣 now I understand how it works, they literally fuck each other because they're beside each other 🤣🤣🤣

He said law grown hes calling me

"caracteristicas" ?? : p around 11:13 do u also speak spanish?

Magnetic pull is pulling god away but conductors pull light. quest

How proton moved. Any reason then tell.

next up: Grammars. How they works. Really funny as it is paired with the use of "virtual" and not knowing the full meaning of the word.

Hear light now through conductors and smart phone's medals you have I think you will take over the world to world Peace heroes

If an antenna for Handphone? Maybe sticking at usb, if a shopping centre underground, then a corner to have antenna maybe to use awhile? If a dish style antenna that is small for phone(an external personal choice to buy)?

Radio amateurs talk about SWR. What is it?

This topic were in Physics

Antena theory

Great video but we need to stop use conventional current in a circut. It's very confusing to understand physics. Why electrons are represented using plus sign ?

Magnetic "Lines" form? "Lines" made of what? Don't bother answering, it's like: "Oh but it's a "particle AND a wave at the same time" A "wave" of what? Ubiquitous, but anisotropic in the presence of a mass body, the Aether shall set us free.

Is he friend. In or out Russian war

"How they work", not "how they works."
