The antenna fits inside a sphere of radius 0.0415 wavelengths.
However, the antenna pattern is not spherical and more closely
resembles the torus produced by a dipole than of an isotropic antenna.

An isotropic approximation, which doesn't really qualify for the prize
because the pattern is not polarization and phase insensitive.
