Abstract Dielectric resonator has been implemented in many frequencies and microwave front-end design, where the main focus is on homogeneous (single) permittivity that performed only one purpose at one time. In this article, the parallel inhomogeneous cylindrical dielectric resonator at C-band resonant frequency is presented. The parallel inhomogeneous cylindrical resonator modeled by combining two different dielectric permittivities; Magnesium Titanate and Cobalt Tinatane that have high and low permittivity, respectively. Each permittivity material is divided 90° apart. A parallel microstrip-line coupling is used to excite the inhomogeneous cylindrical dielectric resonator. The parametric study of the parallel inhomogeneous cylindrical dielectric resonator is highlighted to be investigated purposely to identify the impact on any changing parameter behavior and obtain their best configuration of performances. These parametric studies evaluated in-term of configuration the parallel microstrip-line and the effect of angular position inhomogeneous cylindrical dielectric resonator. Different types of configuration microstrip-line are tested, i.e. coupling spacing and curves configuration at λ/4 of wavelength. The return loss at the input port of parametric study in-terms of coupling coefficients is satisfactory at 17 and 19 (mm) of parallel microstrip-line for same-port positions. Meanwhile, the investigation into parallel microstrip-line curve configuration at λ/4 of wavelength indicates the best performance at curve configuration of 155° with 9.77% improvement on 5 GHz resonant frequency. In conclusion, the optimum performance of inhomogeneous cylindrical dielectric resonator at 5 GHz is performed when coupling distance of 19 mm with 155° curves positions of parallel microstrip-line without the angular position.
