An antenna apparatus for a radio frequency (RF) coil to transmit signals to and to receive signal from a subject in a magnetic resonance imaging (MRI) system includes a distal surface facing away from the subject, a proximal surface facing towards the subject, a high permittivity material (HPM) having a shape, and an antenna coupled to the HPM and positioned on the proximal surface such that the antenna is positioned between the HPM and the subject.

There is provided a method of producing a device for manipulating a magnetic field of RF radiation from one or more RF antenna in an MR system. The method comprises: determining a target resonance quality factor and/or a target resonant RF frequency of the device based on at least one characteristic of the one or more RF antenna; determining a design of the device to provide the device with the determined target resonance quality factor and/or target resonant RF frequency; and making the device in accordance with the design. The device comprises: a plurality of conductive elements arranged in an array, wherein the array is arranged to redistribute energy between electric and magnetic fields of the RF radiation at a resonant RF frequency when receiving the RF radiation, the RF radiation having an RF wavelength greater than a respective dimension of each conductive element; and a dielectric material, wherein the dielectric material has a dielectric permittivity and a loss tangent.
