Endoscopic Capsule

A resonator for magnetic resonance applications comprising:

• a conductor element extending in an extension direction and configured to operate with a resonance current at a resonance frequency oscillating in the conductor element in the extension direction, said conductor element being tuned to said resonance frequency and having a total length in said extension direction that is smaller than half of a wavelength of the resonance frequency;
• said conductor element being a multi-layer conductor comprising a plurality of layers that are electrically insulated from each other;
• in said extension direction, the respective layers having layer ends that are capacitively coupled with each other;
• and
• said multi-layer conductor being configured to cause layer currents, forming said resonance current at said resonance frequency, to flow in the respective layers in said extension direction that are substantially equal in magnitude relative to each other.
