Title: Help to draw Minkowski geometry for design a fractal antenna Post by: jlcortex on April 27, 2012, 11:02:24 PM Hello,
I am trying to design a fractal antenna like this: (http://www.fractenna.com/crankcomparison.jpg) (http://images.wikia.com/whitecollar/images/3/3a/Adler's_Fractal.svg) I can draw it with CAD program but i would like to unsderstand how exactly are this drawn. it seems is a kind of "Quadratic Koch curve" or "Minkowski" I have played with a online l-systems fractal generator aplication: http://www.kevs3d.co.uk/dev/lsystems/ I can get this kind of fractals but i can not generate this exact shape. it seems it needs some reduced indentation so wire don't short-circuit like this: (http://n3ox.net/files/it3.jpg) Is it possible to build it with L-System? I would be grateful if anyone can help me draw this fractal!!! Thanks jlcortex Title: Re: Help to draw Minkowski geometry for design a fractal antenna Post by: matty686 on July 26, 2012, 04:19:30 PM Hmm Lets see if i can solve this it looks easy
but I can't solve it conventionally but i will try to show you one way to solve it give me about an hour Title: Re: Help to draw Minkowski geometry for design a fractal antenna Post by: matty686 on July 26, 2012, 04:36:33 PM ok i tried too using the Qfractal method but i got the same pattern you did
ill try again later Title: Re: Help to draw Minkowski geometry for design a fractal antenna Post by: cKleinhuis on July 26, 2012, 04:43:39 PM consider that you confuse the "touching" because the antenna is a modified version, and basically you reach some points exactly as before, e.g. the center square, each corner is reached 2 times, but you have to make sure that on second visit you do not touch it anymore, i think the basic idea comes out of such a system, but it is hand-modified to achieve non touching crossings ...
