Power Distribution
Characteristic Theoretical Solid Angular Power Distribution of
the Semicylindric Carrier Calculated by the Visual Studio 2008
C++ Implementation of the Model (See Below). 1024 Radiators
denoted by red dots; locus of observing points - black;
normalized radial coordinates. Both the Linux g++ & the Visual
C++ Implementations are Due to the Author. The Characteristic
Distribution of the Semicylindric Antenna is Represented by the
Java3d Visualiser Written By the Author.


Problem: Given the coordinate systems of the antenna & of the observer at rest in the coordinate system of Earth.

Objective: Rotate the main lobe, such, that it illuminates the receiver.

Accomplishment: Let all the radiators be fed by equal current with no mutual phase shift.
Under these circumstances the system radiates the structure of the
highest symmetry, i.e., at given directions there may exist overlaps of more than a single lobe (state).

  1. Define the cell (class of radiators) by choosing the range of polar angles & of azimuths.
  2. Define the phase shift for members of this class respective elements belonging to the rest set.
    The phase shift breaks the symmetry of the radiation distribution by rotating different states by different elongations.
  3. Additionally increase the intensity of currents powering the spirals belonging to the same cell:
    the given lobes are additionally enhanced respective the others.

Low directional efficiency (cell flow - to set difference flow - ratio) corresponds to high waist of power.
But the objective can be fulfilled.
