FIELD: radio engineering, communication.
SUBSTANCE: invention relates to microwave engineering. A radio-frequency (RF) transmitting and/or receiving antenna is particularly in the form of a coil structure or coil or loop arrangement, having one or more removable conductors, especially for use in a magnetic resonance imaging (MRI) system or a magnetic resonance (MR) scanner, for transmitting RF excitation signals (Bi field) for exciting nuclear magnetic resonances (NMR), and/or for receiving NMR relaxation signals. The RF antenna is provided such that it can be easily adapted according to an application which either requires a large opening through the RF antenna or a parallel imaging capability.
EFFECT: high sensitivity of the RF antenna and image quality.
