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.
