Substituting the conventional Radio Frequency coil (RF coil) with a patch antenna has the potential to increase the magnetic field homogeneity in large Fields Of View (FOV). The homogeneity can be improved even more when two of these antennas are facing each other. The size of the patch antennas needed to be reduced to fit inside the scanner bore to use them as RF coils. This was done via inserting high dielectric material plugs. The two facing patch antennas system was also fabricated and tested.
