I read the patent application meantime. But I must say there is not much
content in it. Especially nothing how to calculate dimensions, materials or taken measurements. My understanding is that it is a helix antenna supported with a ferrite powder rod in the axis. And it is electrical much longer than the wavelength used. Adaption to the "ether" field Z(0) with up to 4 stages of different winding/mu(r) value materials. A magnetical antenna very similar to the electrical Yagi antenna. "The antenna works up to 500MHz", he says. "Greater frequency requires lower mu(r)." Sorry, maybe it won't work at all. I'm not an antenna expert. Maybe the author of the patent will directly respond here sometime? What do you think? - Henry Arie de Muynck schrieb in Nachricht ... "Henry" wrote You made great interesting experiments! The electrical field will suffer with a alumni foil, surely. Magnetics will go thru. You didn't do the experiment. Regards, Arie de Muynck |

When I read this thred, I remembered about an antenna that would not need a
ground plane, This enabled celphones 65% gain from amtenna looses to body and surroundings. It was a cylindircal helix, very short. I understood it to be an antenna with differential emission, coaxial electrical feild perhaps. gagir "Henry" wrote in message ... I read the patent application meantime.

I'm not an antenna expert. Maybe the author of the patent will directly respond here sometime? What do you think? I'm not an expert either, I just got triggered by the nonsensical "will work even when cast in metal" thing. I've constructed enough RF electronics to know when even a thin layer of copper (or aluminium) will shield EMC almost perfectly (closed box aka Faraday cage). I checked the Norwegian patent office but they cannot afford a decent free publication site like the US has. Do you have a link to the patent or would you care to send a copy to (a temporary address)? Oh yeah.... do try the experiment and be amazed... Regards, Arie de Muynck |
