Abstract
A radio frequency antenna for a nuclear magnetic resonance tomography apparatus has interior conductors which form a transmission line resonator with at least one shortening capacitor. The transmission line resonator can resonate at a plurality of resonator frequencies, and a trap circuit is provided for decoupling the interior conductors from the other conductors. The antenna can be operated at a number of different resonate frequencies, for example, at frequency f.sub.1 =170 MHz for protons (hydrogen) and F.sub.2 =69 MHz for phosphorous.
