Patent ID: 7564244

Claim:
A radio-frequency (RF) resonator system, in particular, for a magnetic resonance (MR) probe head, the system comprising at least one RF resonator, the resonator comprising: a substrate; a conductive structure applied on said substrate, said conductive structure having regions of capacitive and inductive elements; and at least one dielectric layer applied to said conductive structure to coat and at least partially cover said regions of said capacitive elements, said at least one dielectric layer having a local thickness set in dependence on a resonance frequency of said RF resonator prior to coating, on a defined resonance frequency of said resonator once it is coated, on a dielectric constant of said substrate, and on a dielectric constant of materials of said at least one dielectric layer, wherein deposition of said at least one dielectric layer is performed using at least one of evaporation, plasma deposition, sputtering, or deposition from the gas or liquid phase, wherein material of said dielectric layer exhibits a dielectric constant similar to that of said substrate or, wherein a dielectric constant of said dielectric layer is between half and double the value of a dielectric constant of a substrate.
