## Details

I’m looking to have a design created based off of the sketch provided.  The image will eventually be imprinted on a circuit board as an antenna so it can be designed in basic black with a white background.  The image is basically a fractal pattern similar to tree branching that branches off and expands in Phi Ratio proportion (1 to 1.618).  If you Google “fractal pattern” you can learn more about them and what they are as well as the Phi ratio.  The overall size of the image isn’t as crucial as much as the angles of each branch remain a constant 36 degrees and the branches’ lengths are each in Phi ratio proportion to the branches before and after it.  So basically, the design starts as a straight vertical line and then is split with two additional branches (at the Phi ratio point being .618 of the total length).  Then this pattern of splitting repeats again and again.  I only drew several levels of splits on my hand drawing and then stopped but perhaps with the accuracy of a computer, this drawing when done more precisely can continue at least one more level of splitting.  This particular drawing is approximately 8” tall but it doesn’t have to be that size at all.  It can be larger.  As long as angles and proportion remain the same.
Also, I was hoping that perhaps the branching thickness of this fractal could also exhibit the Phi ratio.  So as the branching continues upward, the branches get thinner and thinner.  I didn’t draw it this way in my sketch since I was only attempting to show the basic pattern.  Perhaps the ratio could be such that from the very base of the design to the first split to the first branches, the ratio of thickness could be in Phi proportion.  And this would also continue as well throughout the design.  Basically, from each split to the next one, the branch narrows to a width of .618 of the thickness of where the branch began.  You can see the gradual taper of branching in a second image that I can send you.  The quality is poor since I did it in Microsoft Paint lol.  But you should be able to get the idea.  If it’s easier though, maybe the basic design should be done first like in my sketch, before branch thickness can be added later once I’ve seen the basic structure.  Any questions, feel free to ask.  Thanks a lot.- Joe
