  We report decoupling of two closely located resonant dipole antennas
dedicated for ultra-high field magnetic resonance imaging (MRI). We show that a
scatterer slightly raised over the plane of antennas grants a sufficient
decoupling even for antennas separated by very small gap (below 1/30 of the
wavelength). We compare the operation of two decoupling scatterers. One of them
is a shortcut resonant dipole and another is a split-loop resonator (SLR).
Previously, we have shown that the SLR offers a wider operational band than the
dipole and the same level of decoupling. However, it was so for an array in
free space. The presence of the body phantom drastically changes the decoupling
conditions. Moreover, the requirement to minimize the parasitic scattering from
the decoupling element into the body makes the decoupling dipole much more
advantageous compared to the SLR.
