Flexible Antenna

[SimonH]

Hi,

I'm trying to find some information on an antenna design I saw on
Tomorrows World a few (probably 10) years ago.

This is my recollection of it :
It was made of concentric circles of foil and was completely flat. In
the demo they recieving satellite tv on a roller blind with it on. I
seem to remember them saying it was invented during the second world
war.

Any ideas on what it is called or where I may be able to get more
info?

cheers in advance

Simon

Hi,

Sounds like some form of Fresnel antenna. Have a look for one of
the SETI groups as I know that they have kicked the idea around. It is
a thick (three-dimensional) device however and not just metal circles
on a substrate.
