Plasma antenna; Junk Science or Practical Application - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Is this http://www.scientificblogging.com/news_account/stealth_antenna_made_of_gas_impervious_to_jamming actually of any use?

The guys that came up with it say it is "impervious to jamming" ; huh? what-the-heck ?

This antenna is for the battlefield? Wouldn't it be cheaper to just aim searchlights onto your existing antennas and paint them bright colors?

I assume the antenna will work. The ionized gas in the fluorescent lamp should work just like a fat wire.

But WHY? Can this actually have some real application other than an educational demonstration?

Hi wb9jtk,

I took look at the article given by your web link, in my opinion, it may be used for some special applications such as transformable antennae. As we know, there must be certain trade-off to implement a wideband or multiband antenna due to the fact that the most antenna structures are not adaptive to the frequency variety. So if this kind of antenna can be implemented in a flexible pipe which form is driven by signal, it may be a candidate of adaptive antenna.

It is what I imagined.
