...asking if he really meant 13.56 MHz...

"John Smith"
Yes, GHz would make much more sense.

Except that 13.56 MHz is a very, very well known (common) ISM
frequency.

....well, perhaps not as well known as it might be... ;-)

Amusingly, most of the 30 Google hits on "13.56 GHz" are errors where
people have incorrectly assumed GHz for such RFID usage.

Stripline at HF ?? Geesh... I supposed if you've got the 'real
estate'.
