The antenna was first patented in Norway this summer, and I have just read
that patent. I think the innovative aspect of it is the ferrite and its
properties which makes it feasible for a transmitter at VHF/UHF at
reasonable power levels and
with a size of only a few cms.

Of course, the patent says very little about the ferrite - I guess that's
how a good patent is
supposed to be written. The antenna is in use for tracking of sheep and it
is being evaluated by the Royal Air Force (UK), so I think there must be
something to it, see

Has anyone looked at this patent?

See http://l2.espacenet.com/espacenet/viewer?PN=WO0245210
It's basically a coil wrapped around a ferrite rod/tube
that sensitive to the magnetic part of the electromagnetic
field.

The author claims it can be built small, handle high
power, and is mostly omni-directional.
