In the previous work, we evaluated the transmit performance of 10.5 T RF coils composed of dipole antennas and high dielectric constant (HDC) ceramic materials with a “Normal” (Dipole - HDC - Sample) and a counterintuitive “Flipped” geometry (HDC – Dipole - Sample) positioning. Now we evaluated the receive performance of such an array structure with these setups both in simulations and experiments. The “flipped” setup showed notable periphery SNR improvement and suggest some promise for the UHF receiver arrays.
