Spray-on Antenna

at 2:50 pm. Filed under Crazy Hacks, Insane Equipment


This Spray-on Antenna could revolutionize RF transmissions if their claims are true! Apparently nano capacitors are sprayed onto almost any surface to make it a powerful antenna.


 “The company is promoting it as a multi-purpose antenna, simple and quick to assemble, mountable on almost any surface, for use in any environment. “Any” bears quite a range of possible end uses.”

    Sounds pretty much like BS. The spray probably contains metallic particles, so spraying a surface creates a metallic area that can serve as either a capacitively coupled antenna or a reflector surface. (A capacitor doesn’t make an antenna…) For efficiency, one does however need certain shapes and sizes for certain frequencies, simple spraying will only improve reception if your antenna was crap in the first place – which applies to almost any cellphone antenna. Remember the times when cellphones still had “external” antennas, even extendable? Those were pretty crappy already, but worlds better than what we use now.

    Besides: “From the depths of the ocean to outer space” – sorry, water does not like to let electromagnetic waves pass. Submarines must use VERY low frequencies (a few dozen kHz) to transmit when submerged, a cellphone (even with superduper external antenna) would fail to be received outside the water after about one or two meters down into the water.

    IMHO someone is hoping to revive the dotcom era, trying to sell fairy dust…

    As soon as I heard “from the depths of the ocean” my BS meter pegged. Next “Cop car antenna burning the hell out of you” steaming BS. I am sure he will get a couple million from Darpa.

    I call BS!

    Bad post, Hacked Gadgets. This is nothing more than hyped-up nonsense.

    If this is true he should just show a demo or something. Not sure about the validity of this particular company/product , but one should not disregard the idea entirely. Fractal-shaped antennas look funny but are highly effective (and used in all cell phones today). Theoretically it is possible to create such an antenna on the nano-level . He is pushing the “capacitor” idea which I don’t understand (and maybe it is BS after all), I would probably go the route of a long conductor, somehow the nano-particles should arrange themselves in a fractal shaped antenna , not totally impossible.

    He uses the term “standard antenna” far too often for my liking. What kind of antenna? Dipole? There are tons of different types that all have staggeringly different characteristics.

    If they’ve actually found a way to have less ohmic loss in antennas – convert more of the energy to actual RF emissions rather than heat in the antenna itself – then that’s huge. This alternatingly hand-waving / slightly technical (Oooh! He said dBm!) description doesn’t give me any confidence that they’ve done that.

  7. Mike Says:

    Yes, one should disregard the idea entirely. The product was not demonstrated nor submitted for testing. We don’t live in a world where we believe all claims until they are proven false. Therefore, this product (and the post) is pointless.

  8. Matt C Says:

    I have seen these in action, and they work. I could care less if you guys believe me but this stuff rocks

  9. Mike Says:

    Real, experienced electrical engineers say it’s BS. But some random person on the Internet says it works…That’s good enough for me!

  10. Olaf Says:

    “They work” like in “He sprayed it on and then I heard something”? Oh yes, that should be possible, no question. I can do that too with regular metallic spray paint. But if he and you are so convinced of that spray, why don’t you let someone else do a few measurements? Let’s compare it to a standard dipole – on what frequencies btw? Does this work on all frequencies? Why oh why is there no substantial info available…?

    If this technology is applied to a cell phone, what does the increase in power do to your head?

  12. Alan Parekh Says:

    Hi Charles, Hopefully not much!
