... spherical antenna ( ). Other methods of exciting, which allow to get maximum CDD of non-superdirective antenna have significant oscillations of amplitude and phase, which makes it difficult to use them. For the case of exciting a half−sphere with current (1), DD were calculated using an approximate method. Fig.1 DD of spherical antenna, kR =20: — strict computation; — approximation; — DD of the flat aperture. Fig. 1 presents DD of the spherical antenna in case the half-sphere is excited computed using strict and approximate formulas. Also, for the sake of comparison,...
