This study proposes a new 15-channel end-coated half-wave dipole antenna array system for foot/ankle/calf imaging at 7T. The ends of the dipole antennas, operating at 300MHz, are coated with a high-permittivity dielectric material to decrease their length and flatten the B1 field simultaneously. The end-coated dipole antennas are placed around the region of interest to gain the required B1 coverage in the imaging target.
