Koch curve antenna

Latest comment: 10 years ago2 comments2 people in discussion

"The fractal Koch curve antenna approaches the limit." Source or calculation for this very interesting assertion? 84.227.254.143 (talk) 16:41, 30 March 2014 (UTC)Reply

see Puente, Romeu, Pous, Ramis and Hijazo, “Small but long Koch fractal monopole”, IEEE Electronics Letters, Vol. 34, No. 1, pp 9-10, January 1998. I did not consult this, but got it from http://www.ece.iit.edu/~pfelber/fractalantennas.pdf‎. http://ms-thesis-xetb.googlecode.com/svn/trunk/Papers/Thesis%20II/Paper%20Research/The%20Koch%20Monopole%20A%20Small%20Fractal%20Antenna.pdf covers this idea very well.

Underhill reference/claim

Latest comment: 6 years ago1 comment1 person in discussion

Claims that break the Chu limit are contentious to stay the least. In fact most of Mike Underhills on loops etc work is considered flawed/barmy and should not be quoted - esp given third party mesurements and numerous papers — Preceding unsigned comment added by Mjnmjn (talk • contribs) 04:01, 16 January 2018 (UTC)Reply
