RESONATOR THAT CAN BE EXCITED IN HE(21DELTA) MODE

摘要

The invention relates to a resonator (DR), in particular a high frequency resonator, which is approximately cylindrical and is characterised in that the ratio of its height h to its diameter D is between 2.3 and 2.7, in particular 2.5. The resonator can be excited in particular in the HE21δ mode and has a high operating quality. The invention also relates to an assembly, in which the resonator can be positioned between high-frequency lines with a periodicity of μ/4 along said lines. The invention also relates to a method, according to which the resonator can be tuned once mounted on a support material, by the addition or removal of dielectric or metallic materials.
