Due to the parasitic capacitance and increased inductance, building large-size high frequency RF coils, including surface coils for human MR imaging applications at ultrahigh fields, is a challenge. By taking the advantage of high frequency capability and large size of dipole antennas, in this work, we propose a novel surface coil design method using the proposed V-shaped dipole antennas for large-size, high-frequency, loop-type surface coils in ultrahigh field MR applications in humans. The results show that the proposed large size loop-type dipole surface coils (~20cm or ~16cm diameter) have the potential to generate common B1 field distributions of traditional loop-type surface coils at 9.4T (400MHz) and 14T (600MHz). This opens up the possibility of constructing high frequency large size surface coils for ultrahigh field MR imaging in humans.
