Hi Ed--

The  Sierpinsky bowtie you show is not that gentleman's design; it is his 
drawing. The "design" (actually antenna structure) has been recently  
protected through a utility patent (US 6,452,553). 

The Sierpinsky bowtie was first fabricated in 1989. I know; I was the one who 
did it;-) I have built many other fractal antennas before it and virtually 
countless ones since.

As I have often stated, I see no problem with hams experimenting with fractal 
antennas for non-commercial purposes.  In my opinion, please leave the 
drawings up on your web site, and kindly note the proper design attribution 
as mentioned.

On a related item, I do, on occasion, provide select files for simulation by 
hams, but have concerns about copyright infringement (unauthorized use), and 
information getting to those it is not intended for. I can be convinced to 
provide files to individuals with sincere and genuine needs, for the sake of 
ham experimentation. Further discussions with me on this, if any, should be 
via e-mail.

Best to all,

Chip N1IR
