Introduction to Antenna Design #3 // Dipole Antennas

[@acestudioscouk-Ace-G0ACE]

A great series which explains the topics well. Shame there weren't more episodes in this excellent collection.

[@josephrossman1600]

Looks like I found an underrated channel before it blows up :) Subbed.

[@ProtoG42]

Thank you! I just rewatched it for the first time since I uploaded it. I remember really enjoying making this one.

[@maxk4324]

Yours are the first videos that have actually started to help me understand the basics of antenna design. I have been trying to design a twisted birdcage style antenna for inductively coupled plasma generation for years and wile I understand how the antenna radiation pattern generates the plasma (I think) the nfiner details of actually powering the antenna, SWR graphs, and all that have always confused the shit out of me until now (I study mechanical engineering so I have had to approach antenna design from the very basics of electro/magnetodynamics as this is all I have been schooled in).

[@KillerSpud]

I'm enjoying this series. I've had a pretty good idea of whats going on with antennas for a while now, but your visuals are really helping me grasp it better. Keep it up!

[@ProtoG42]

Thank you, I'm glad it's helpful!

[@Terribleguitarist89]

What a beast of an analyzer.

[@GasparinPR]

Hey Proto G, how did you create the vector fields of the antennas at the end?

[@NKaumans]

What I find interesting is router companies using the same antenna for their 2.4ghz radio chains and 5ghz chains. I've also noticed that their range on 2.4ghz tends to be under performing compared to other brands using separate antennas for each band

These are great videos and super helpful. Thanks!!!! Hopefully you can answer a question. I’ve just started to check out PCB antennas. I ordered a fairly inexpensive set recently. Before hooking anything up, I took my multi meter to it. I found that there was continuity between both poles of the sma connector. Is this correct? It seems to me that would negate any properties of an antenna the PCB’s may have. Any insight, information or wisdom would be greatly appreciated. Thanks again.

Hello, is it true that is possible to measure the Antenna gain by placing two similar antennas one meter apart and use two NanoVNA devices?

[@TheElectronicDilettante]

Another question I’ve had… As an avid hiker, ive found myself in serious backcountry with no cell phone signal or reception on my handheld Cobra CB. Could a drone drag a single wire vertically as an emergency antenna. I was thinking of a 1/2 pound of ultra thin copper wire which would yield a couple hundred feet. Has this been done yet? If not, is it feasible. Any thoughts would be greatly appreciated. Thanks

[@MikeDesertHunterHale]

I very much enjoyed this short series... more more more!

[@ProtoG42]

Thank you, I'm sorry I didn't do more of them It was a lot of work putting these together but they never really got the attention they deserved.

[@simonbellemare2289]

Really cool video! What material do you use? For conductor? Is it heat shrink wrapping? Thanks!

[@joshalex8477]

Hey I'm a teenager looking to make an antenna project. Are you able to simply have an antenna on a PCB?

[@wyw4466]

Can you explain how come the wave pattern changed when power is 180 degree out of phase? Thanks!

[@skyemceowen957]

This was incredibly helpful! Thank you!

[@habiks]

Why did you stop with the series?

[@beaconmania]

Could you please tell us what analyser you use for these measurements ?

[@Migueldeservantes]

Awesome work, wish you'll have show the pattern / efficiency of a full length dipole 5.8 Ghz...

[@RosssRoyce]

Where shall i place a tuning capacitor, similarly to magnet loop antenna, in a dipole antenna in terms to make it tunable? Thanks!

[@Migueldeservantes]

Hey, I have been watching every single possible video on antenna tuners that I can find in order to understand everything I can about this devices, I have a modem receiver that have this single wire antennas that come with a ATU unit "Two of them" each have a this totally miniaturized version of it.. but range on this particular unit really stinks. Now its my hope to increase the range by installing a good set of choked dipoles but don't know if I have not other choice but to use the same type of ATU? with the same value on the capacitors & inductor....your advice will mean the world to me!!

[@RobSummers993]

It almost feels like I'm cheating by watching your videos! Awesome content!

[@healingbench3198]

Nice tute, came across you on reddit. Subbed. Hey, what make and model is the analyser? The units ive looked at for 6Ghz are 20k+

[@ProtoG42]

N9917A FieldFox Handheld Microwave Analyzer. The price varies depending on what options you choose. This goes up to 18GHz but they have models that go past 50GHz.

[@neodiy]

The best video i have seen straight to the point...i like this kind of video..u wasted none of my time...you explain as you speak clearly...unlike the rest speak too much no proof....what the device to measure the antenna gain called and brand?

[@clems6989]

What model vna ?

[@vibrion121]

Question: which model is your network analyzer? price? (can't see small screen celphone ;) )

[@ProtoG42]

N9917A FieldFox Handheld Microwave Analyzer. The price varies depending on what options you choose. This goes up to 18GHz but they have models that go past 50GHz.

[@lazarocamargo]

Excellent tutorial

[@Arnthorg]

Can you maybe explain how the meter works and how to use it?

[@ProtoG42]

What are some questions you have that I could answer?

[@power-max]

That graphic at the end tho, impressive! electromagnetic radiation is still a bit confusing to me, I have a hard time seeing how a magnetic and electric field (both of which I understand) can exist as one thing. All I know is that when charges are moving in a conductor they can create the alternating magnetic field shown in the illustration, and the charge of the charges is responsible for the electric field half. That's what I learned in university level physics, still make little sense.

[@ProtoG42]

Thanks, I used this applet to make that visualization: falstad.com/emwave2/ It's a great tool to play around with.

[@tejeshwvardhan1165]

how to make antenna wideband??

[@Un_Pour_Tous]

Perfect video. Thank you

[@alanheadrick7997]

I need a DF antenna for around 3.5 GHz. I need to find interfering 5G signal.

[@Alexelectricalengineering]

Thumbs up :)

[@hasanxnv]

Your notebook has a NASA logo. R u working there?

[@ProtoG42]

I was a few years ago

[@pufferfish0101]

Last!!

[@vibrion121]

i love falstad.com incredible java apps also!

[@ProtoG42]

Me too, this is the one I used for the visualization at the end: falstad.com/emwave2/
