WitrynaGolden spiral. Golden spirals are self-similar. The shape is infinitely repeated when magnified. In geometry, a golden spiral is a logarithmic spiral whose growth factor is φ, the golden ratio. [1] That is, a golden spiral gets wider (or further from its origin) by a factor of φ for every quarter turn it makes. Witryna3 lis 2012 · Can I use other method? python; math; Share.

WitrynaThe utility model provides a television receiving antenna which is mainly used indoors. The utility model is characterized in that a logarithmic plane spiral radiator with sheet band and a reflection cavity, and a structure of inverted feeder with a way of parallel stub central feed are adopted. So the antenna gain is raised from zero or negative value to … The golden spiral is a logarithmic spiral that grows outward by a factor of the golden ratio for every 90 degrees of rotation (polar slope angle about 17.03239 degrees). It can be approximated by a "Fibonacci spiral", made of a sequence of quarter circles with radii proportional to Fibonacci numbers.
