An RF resonator mounted on a dielectric support is operated in quadrature at a selected NMR frequency. The resonator consists of four axially distributed high frequency ring current paths on the support and at least four high frequency current paths interconnect each pair of adjacent ring paths. In the preferred embodiment at least sixteen equally spaced parallel segments connect each ring pair and are aligned with one another. The ring segments between the parallel segments together with the parallel segments form loops. At least one discrete capacitor is placed in each outer current loop thereby interrupting the loop. However, this is done so that no inner loop is interrupted by a capacitor. By using quadrature input/output coupling, either inductive or capacitive, a co-rotating mode is excited in the two outer loops through the inner loops providing a highly uniform field across the resonator.
