The equation of a spherical helix on a Sphere with Radius making an Angle with the -axis is (1) (2) (3) The projection on the -plane is an Epicycloid with Radii (4) (5) See also Helix, Loxodrome, Spherical Spiral WebSpherical images(indicatrix) are well-known in classical differential geometry of curves. Let us define the curve C on S2by the help of vector field () () () Ws Ws Cs . This curve is called the spherical Darboux image or the Darboux indicatrix of ~. Similarly, the unit tangent vectors along the curve ~generate a curve (T) on S2.

Webspherical helix provides 800 MHz bandwidth, while a 10-turn spherical helix has a bandwidth of only 50 MHz [4]. The bandwidth is a small fraction of the operating frequency , thus the spherical helix is categorized as a narrow-band antenna. 3.2.4 Input Impedance The input impedance of a spherical helix operating in the axial mode is complex. tacobell cinnabon coffee ingredients
