High performance Radio Frequency resonators (RF resonators) produce strong and homogeneous magnetic fields. Due to their large sizes, patch antennas have hardly been considered to be used as RF resonators in Magnetic Resonance Imaging (MRI), especially at high fields. In this work, a newly developed miniaturized patch antenna with high dielectric material plugs was designed, simulated, built and tested at 14.1 T. The simulated and experimental magnetic fields were compared to confirm the performance of the fabricated patch antenna as a RF resonator for MRI.
