Have you ever built one and measured its radiation pattern?


Hi Chris,

Others have - the design is not unique to me and has been around for
years. I modeled it to merely confirm those reports and that was
rather simply accomplished. I have reported these results to
interested parties here for the last 10 to 15 years. I am under no
illusion that Art has ever used that data as a resource, otherwise it
would undercut his claim of novelty.

I've no doubt that other designs meeting your terse requirements could
be rummaged up. I have no presumption that NEC fails for this one
specific design that is ordinary in every regard to conventional
modeling. At a minimum this is only 4 wires. As such, I am
satisfied.

Good. Maybe this will encourage Art to have a go at my challenge by
applying his own theories then.

I had seen papers about inverted F antennas before (at an IEE or IET
symposium some ten years ago), and I vaguely recall hearing that some
manufacturers use them in mobile phones, but I'd never seen a pattern as
uniform as the result of your simulation.

Chris

art will never accept your challenge. its up to you to prove that his
assertions are incorrect... and then get ignored as he continues to state
the same things in many different forms. unless you can capture one of his
diamagnetic levitating solar neutrinos and show that it doesn't sit on the
antenna element and jump off when a pulse of current hits it you will never
be believed... and even if you did capture one he would tell you it changed
in flight from the sun.
