摘要：
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.
