That kind of tight, uniform spiral is called an Archimedean spiral (aka Archimedes spiral). Most of them are produced by formulas. The Archimedes spiral antenna is fixed and supported by foam with thickness of 70 mm, and the foam has little influence on the performance of the device. If a spiral is made by two motions about a point that is, a uniform motion in a fixed direction and a motion in a circle with constant speed, both motions start at the same point. Basically, Archimedes screw turbine is the type of wind turbine having the same working as that of the traditional wind turbine.

The Archimedean spiral (also known as the arithmetic spiral or spiral of Archimedes) is a spiral named after the 3rd century BC Greek mathematician Archimedes. Also shown is the curve given by , (red), and its intersections with the spiral (purple boxes). You can give normal component. In the case of the Archimedean spiral patterns, either an overall uniform distribution of the readouts is achieved with the straightforward interleaving approach (type A) of (a.1) and (a.2) or the displacement of successive readouts is minimized with the rotation-based approach (type B) of (b.1) and (b.2). For my project they're way too far apart. Impulse generator produces a short-time pulse synchronized with the oscillator, amplified, and applied to the transmitting antenna. Figure 6.
