  We study scattering phenomena such as the Kerker effect, superscattering, and
scattering dark states in a subwavelength atomic antenna consisting of atoms
with only electric dipole transitions. We show that an atomic antenna can
exhibit arbitrarily large or small scattering cross sections depending on the
geometry of the structure and the direction of the impinging light. We also
demonstrate that atoms with only an electric dipole transition can exhibit a
directional radiation pattern with zero backscattering when placed in a certain
configuration. This is a special case of a phenomenon known as the Kerker
effect, which typically occurs in the presence of both electric and magnetic
transitions. Our findings open a pathway to design highly directional emitters,
nonradiating sources, and highly scattering objects based on individually
controlled atoms.
