Dual Band Wifi Panel Antenna

[@terence79chan]

Thanks for sharing this. For a vintage, it has a nicely-designed matching network. Each T-joint has two (100ohm to 50ohm) transformers (fat sections of trace lines) to phase 2 pairs of squares (each square is a 100ohm patch and a pair is basically a 50ohm 8db antenna). 4-squares array is 11db, 16-squares array is 17db, 32-squares array is 20db. A well- thought out layout that packs 20db of gain! :)

Hi, how can this be anarray, does that not need digital control to manage? I thought you make your ant to the set measurment of your freq but if you go over it changes the freq? in this case, by adding more elements how does the freq not change? So confused. Thanks in advance if you do reply and any idea why he does not upload anymore?

"Built down to a price." What a useful phrase! 😀

[@heijerpc]

Interested to see if changes really help. Nice and interesting video as always

[@djtahir7752]

Good job sir ...keep it ...

[@andrewmcneil]

Thank you, I will

[@Manishkumar-dj6kl]

@@andrewmcneil sir can we use dual band 2.4ghz and 5ghz antenna in single 2.4ghz wifi adaptor?is this work?

[@diff_lab]

Plz make those changes and show the network analyzer. It will be fun to see the changes.

Always love your videos very informative 👍 Kindly plz do a video on Mimo patch antenna, thanks alot 😊

[@chrismorris6135]

Would b neat to c how the improvements would compare to the factory

[@chrisarmstrong2721]

Would be awesome to see

[@debashisdas7557]

Hello sar I always watch and love your videos and learnd a lot about antenna.. but the problem is that I cannot replicate those due to poor material and Hardwear availability.. this antenna is perfect for me I have coper clad boards and steel plates which i can etch to build this perfectly.. i would love it if you could provide all the necessary dimensions for this antenna🙏

[@theking-lr2yy]

great video ❤❤

[@Dr_Wrong]

Show us how you'd flow solder onto these types of panels! Yeah? 😃

[@meowwoem6372]

are you going to have a go building your own version?

[@keymaster2108]

can you make a video with 2 or 3 failed ebay 2.4 ghz helical and apply changes to make them work. ty for the videos mate

[@Sandeepkumar-vw5bg]

Keep going ❤️ nice

[@chrisarmstrong2721]

Is this an array? How is this duel band, looks just 5.8? If this was 5.8 how would it look diffrent? Could this be made larger, how big could it go. By adding more elements, is there a greater poer draw? How can a set mesurment for 5.8 allow for additional elements that are connected and not be parasitic like on a yagi? Wouldnt adding additional elements change the freq? What about the reflector, is that not sup to be a certain measurment, if so how can this be so big. Please do assist as really interested to hear back :) Thanks

Recently I was looking at some PCIe cards from laptops. I see cards with 1, 2 or 3 antenna connectors. Most common seems 2 connectors, sometimes marked as GAIN and AUX. I noticed that the 2 antenna's in such case do differ in design. Is that an 2.4 and an 5G antenna? How to tell the difference? So why is called GAIN and AUX? On an HP desktop with such an 2-connector wificard built in, there was only 1 antenna connected. This antenna was attached with is metal part to the metal front of the computercasing. I'm wondering if that helps or disturbs the antenna characteristics?

2.4, 5, and Bluetooth

[@jameslamb4573]

Please mod it just to find out how much better it could be.

[@theking-lr2yy]

What is the distance between square and square،Should this point be taken into account?

[@maplewireless2512]

From the circuit structure, it does not look like a dual-frequency circuit

[@onriview]

are you interesting make it grid antenna 2,4Ghz 24dbi sir?

[@DrGreenGiant]

Could you explain why the traces going to each element seem to keep changing their width?

[@RaffaelloKWOS]

they change thickness because they are adaptations to the impedance. For example, you go from 100 ohms, the thinnest, to 50 ohms the widest part. Or it's 75 ohms. Now I don't see the size

[@terence79chan]

Hi Simon, I posted a video tutorial on how to use different thickness of trace line to phase multiple patches to make a high gain antenna, you should find the answer you are looking for. Just search “Terence Microstrip Array” and the video would show up.
