Many RF coils have been developed to solve field non-umiformity
at ultra-high field. Recently, radiative antenna type
with poynting vector has been proposed at UHF. This
abstract is to evaluate newly developed radiative
antenna type coil, Extended Monopole antenna Array with
individual Shields (EMAS) coil at 7T. To analyze, we
calculated simulated B1+ field and specific absorption
rate (SAR) with Monopole antenna Array (MA), Extended
Monopole antenna Array (EMA), and EMAS coils. Then the
simulated results were compared with the experimental
results. The EMAS coil successfully extended the spatial
coverage with uniform B1+ field distribution.
