We evaluated the performance of 10.5T RF coils composed of dipole antennas and high dielectric constant (HDC) ceramic materials placed in close proximity to the dipole antenna. We investigated the impact of the location of the HDC material relative to the dipole antenna. Both simulations and experimental verification indicate that a counterintuitive “Flipped” geometry positioning the dipole between the HDC material and the sample shows notable improvement in terms of the B1+ efficiency. We suggest further exploration of this new setup for ultra-high field (UHF) transmit arrays.
