At ultra-high field (UHF) MRI, dipole-based antennas have deeper field penetration but increased specific absorption rate (SAR) levels than loop-type coils. In this work, a novel RF coil is proposed based on layer-configured dipole and multiple radiating elements. The designed RF coil is compared with a conventional dipole antenna in electromagnetic simulations and it is observed that more than 30% SAR reduction can be achieved with improved B1+ efficiency.
