Abstract: In this paper, two different methods for the determination of
resonant frequency of parallel plate type uniaxially anisotropic multilayered
cylindrical dielectric resonator are firstly presented for dominant
TE_{0ml} and TM_{0ml} modes. The
first method called as Effective Permittivity Approach (EPA) mainly depends on
the determination of single effective permittivity of the multilayered
structure. The second method, Weighted Frequency Approach (WFA), depends on the
evaluation of resonant frequency of the multilayered structure by weighting the
resonant frequencies of each layer. Obtained results using these two approaches
are close to each other indicating resonant frequency of uniaxially anisotropic
multilayered resonator can be tuned by adjusting the segment parameters.
Therefore, in its multilayered form, cylindrical dielectric resonator designed
with uniaxial materials will exhibit some advantages over isotropic single
layered resonator providing flexible operational characteristics. According to
the presented results, application areas of cylindrical dielectric resonator in
its proposed form will increase especially in future microwave and
communication systems applications as a promising structure.
