Computer model experiment

.... The radiation was 35 db in a shape close to that of a sphere. (when the resistance of the aluminum dipole went to zero the radiation went to a perfect sphere) The radiation was "35 db" compared to what reference value? BTW, a single, linear radiator cannot generate a perfectly spherical radiation pattern, no matter what your model tells you. Even an "infinitesimally" short, center-fed linear dipole has a figure 8 radiation pattern with a directivity (gain) of 1.5 X, or 1.76 dBi -- see any antenna engineering textbook. RF |
